Public bug reported:
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.
