CentOS 8.x openvpn client troubleshooting
Bad compression stub decompression header byte: 102 error
It is possible that while connecting to a VPN server (Could be firewall eg sophos or a openvpn server), that client receives error such as:
Bad compression stub decompression header byte: 102
These are often seen only while initiating a new connection to particular machines. This can be due to disabling of lzo-compression in configuration. To fix this edit the openvpn configuration file and update 'comp-lzo' from no to adaptive as:
comp-lzo adaptive
After this during connection you should not see the same error.
This is valid from openvpn 2.4 onwards. So you can also validate openvpn version using 'rpm -qa openvpn' before making above change.
