Connect Client 2.2.90.1104 SSL VPN error: 0x20000000 / 0x0000274D

Question

Had a few Win10 clients recently that received that error when they tried to establish the SSL VPN connection. 
 The issue could be resolved by a client restart. 
 As I've never seen that error, can you please describe what it means? The log looks like there is some issue with the openvpn service but it was running. If it was'nt the error would have been different.

In our situation with an SSL VPN error: 0x20000000 It turned out somehow the date/time got set to 2084. We corrected the time/date in the OS and reinstalled.

Hi LHerzog, 
 Thank you for reaching out to Sophos Community. 
 I've found a similar case where user experiences an SSL VPN error: 0x20000000 
 
 The main ISP was down, and the other alternate ISP was in the backup. Updated the alternate ISP from backup to Active, Connected successfully. 
 Gateway IP Address wasn&rsquo;t added in the configuration. Re-input and re-download the config file tried to ping and got the replies successfully. 
 
 Kindly check if this is applicable to your case and if the gateway IP Address configuration is still the same when the issue re-occurs .
