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.

I tried it for a bit with the old Artful kernel without issues. As soon as I booted back into the Bionic 4.15 I was unable to connect to the VPN again. It might be worth mentioning that the Cisco VPN tool also failed to connect. I did not try that one with 4.13.
