Public bug reported:
Its being reported since 19.10 that open connect trows the following
error after the connection has been established. I noticed that I would
be able to connect the company VPN but connection to certain company
sites that might be accessible from outside will timeout this indicates
some routing issues. the bellow errors are thrown all the time
Error: ipv4: Invalid values in header for route get request.
