I have a similar issue with a Pulse Secure VPN After some time and usually after one or more hex dumps were displayed, I get the following
SSL read error: Error in the pull function.; reconnecting. SSL negotiation with ... Connected to HTTPS on ... Got HTTP response: HTTP/1.1 101 Switching Protocols After that the VPN isn't working anymore and I neet to reconnect. OpenConnect version v8.05-1 Using GnuTLS. Features present: TPMv2, PKCS#11, RSA software token, HOTP software token, TOTP software token, Yubikey OATH, System keys, DTLS, ESP Supported protocols: anyconnect (default), nc, gp, pulse This version is included in Ubuntu 20.04. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1754601 Title: openconnect has trouble maintaining a VPN connection Status in linux package in Ubuntu: Triaged Status in openconnect package in Ubuntu: Confirmed Bug description: Some time after upgrading to Bionic, I have found that openconnect has some trouble keeping a VPN connection open to our company VPN. Since openconnect in Bionic seems to be based on the same upstream release as in Artful I assume that the problem is more likely to be in the kernel, and the timing of when it started could fit the kernel upgrade from 4.13 to 4.15.. I regularly see this in the output: SSL read error: Error in the pull function.; reconnecting. SSL negotiation with <server> SSL connection failure: The operation timed out sleep 10s, remaining timeout 300s SSL negotiation with <server> SSL connection failure: The operation timed out sleep 20s, remaining timeout 290 ... Interestingly I just now saw it recover from that problem for the first time I am aware of. I know that it would make sense to test it with the old kernel, and I will try that some time (I don't reboot that often, and am not always on VPN). In the mean time, I am creating this report in the hope that it will ring some bell with someone.
