Cox started to disconnect VPN

It just started today, my VPN is getting disconnected in less than 1hr. I tried 2 VPN providers and one of them even have a Stealth mode that even the Chinese GFW couldn’t detect, yet Cox was still able to detect it. Has anyone experienced this recently? If so, what protocol can still bypass Cox’s detection? Thanks.

Edit: Looks like the Cox Business Rep deleted his posts. I guess he did find out his company is doing something with residential accounts and VPN. Well, I’m going to try out V2Ray, if Cox can detect that, then fine, you win. I’ll have to rent a seedbox I guess.

Edit2: Looks like all VPNs are blocked. Well done Cox. Nord, Windscribe, and Seed4Me can no longer connect to any of their servers. It’s actually kind of scary impressive. I guess with the recent advances in AI, it’s now trivial to identify VPN traffic. Well, I’m going to get a seedbox for now. Too bad T-Mobile 5G home internet is not available at my address yet, but fingers crossed that they will be available and they won’t use sophisticated VPN blocking methods like Cox.

VPNs can be real volatile sometimes. If you’re using WiFi on a VPN, don’t do that. However, if you’re hardwired and disconnecting, it could be the VPN.

However, it could also be your upload speeds. I’d your upload speeds are dropping out, then could be a symptom of possible packet loss. Do it hardwired and then run speed tests OFF of the VPN when you drop

They aren’t blocking your vpn… it is probably your connection losing sync, packet loss, or any other # of issues that could cause an issue with a VPN.

I use COX, I was having problems with my nordVPN too. Nord does seem to be having some buggyness going on. I contact their support and by toggling off the advanced security , specifically the anti-malware, I was able to get a stable connection going again. I was able to turn the anti-malware back on and everything kept working. Why a simple restart or reinstall doesn’t resolve this is beyond me but that’s what worked in my case. Hope that helps anyone reading this.

I get disconnected all the time. That’s without VPN of any form and hardwired. I think more generally Cox just sucks.

I am having the same issue. I can verify this is true through rigorous testing, it drops internet connection to all devices upon detecting vpn traffic within an hour. When changed persistently it eventually catches on at least 2-3 times a day cutting my streams short and ruining most online gameplay. Only happens when running the most expensive and high quality vpns available so I don’t want to hear some 40 yr old that thinks they still know the internet say it’s not the vpn.

I am on a residential account and have not been booted from work VPN or Windscribe on my personal PC. Wife also WFH on a VPN with no issues.

The only VPN issues I have experienced were during service issues. Unfortunately Cox service is not great. Very intermittent.

I’ve used VPN on both residential and business. No issues. Would take a look at your vpn provider.

it’s most likely the VPN. I used Torguard for a while but most public places seem to block their IP addresses(tried out a lot of servers). You also couldn’t watch any streaming services on it either. Another issue is i couldnt get more than 3 down and 300kb up on it but trying it out on another pc i didn’t have much issue.

VPNs sadly i think are getting blocked by most places and have a lot of stability issues imo

I am going to Necro this, It’s more than likely your local DHCP is set to 1 hour lease times and is changing your LAN IP address. Or there is a setting in the VPN client. I have run VPN servers on a Cox Residential internet and multiple IPsec tunnels and never had an issue on the Cox end.

I don’t know if OP found a solution but it definitely looks to be something wrong with the Cox network, GlobalProtect VPN keeps disconnecting for me too, this has been happening for months, not only the one for work, but also for school, on two different devices, wired and wireless, however, when I use a hotspot from a different ISP it works just fine all day with no disruption, the problem only occurs while on the Cox network, something is not right.

@cox rep: I’m not sure what legal, technical, or logistical loophole allows you to deceive your users by saying that you all don’t block VPNs, but the fact of the matter is nobody believes cox and consequently nobody believes anyone who works for them. It is widely acknowledged to be the worst internet service provider in the United States and the one with the most inept legal representation (being the only major ISP to consistently fail at protecting itself with the safe harbor provision), and consequently punishing its users for It’s own legal and technical shortcomings with vicious internet speed throttling unlike any I’ve ever seen, The limiting of usage to the outright banning of VPNs, and now, the cherry on top, monitoring forums of disgruntled cox users discussing these morally dubius business practices…and then chuckles to himself … actually denying what all of us are experiencing. As if we’re all just gathered here to insult Cox for no reason other than to entertain ourselves. We are here because what we are saying is reality. Cox rep, You are here because you are being paid to gaslight us or because someone is gaslighting you. Either contribute to this conversation by whistleblowing on the devils. You work for, quit and get yourself morally acceptable job, or get out of here because you are definitely not wanted.
I am forced to use cox because there are no other solutions in my area but as soon as there are or satellite internet becomes reasonable than we are gone.

Don’t lie, yes you do. Started experiencing this recently and guess where the Internet led me? VPN service disconnected I have access. I connect to my VPN and as soon as cox detects it I am disconnected. Disable my VPN and voila. What a boot licker

Yes, technically it’s not a block, I’m just getting disconnected every 1-59 mins. It’s consistent with the behavior of VPNs getting detected and reset by the ISP when I was in China. I didn’t know this sub is monitored by Cox reps. If anyone knows how to bypass the disconnections, please PM me instead of posting it here.

Cox Panaromic WiFi does block VPNs

I have had the same issue with my company VPN using an Aruba RAP to connect to corporate. My VPN would disconnect and reset every 10-15 minutes. I disconnected the Cox router and installed an old crappy LinkSys router and my problems went away. Cox is definitely doing something fishy with VPNs. FYI, my RAP is hardwired into my network.

I’m using wired connection.

Technically you’re right, they are not outright blocking the VPN, but they are resetting the connection once they detected it.

NordVPN don’t have a good stealth mode, so it’s easily detected. I eventually got another ISP serving my address and I switched to that. No problem so far with VPN stability. But I still use stealth mode just in case.

One of the VPN was actually Windscribe. I even used their Stealth protocol which was able to get pass the China GFW and it still disconnected every few minutes on Cox. I tried another VPN that didn’t have stealth mode at all and it disconnects every few minutes as well. But I got another small VPN that also has a stealth mode for China and it’s able to stay connected for 1-2 hours before getting disconnected. So I’m guessing Cox might be doing some disconnecting based on known VPN server IPs. That’s why all the people say their work VPN are not affected.
