Hello!
The problem affects those users who run Eddie Desktop edition with OpenVPN and never logged out for more than a year, or use OpenVPN clients with configuration files generated before 2021. Since Eddie Desktop edition re-downloads certificates and keys only when the operator logs in, locally some certificates have expired because we extend their expiration date automatically at least one year in advance (three years normally).
Please try the following procedure to quickly resolve the problem:
run Eddie
on Eddie's main window uncheck "Remember me"
log your account out
log your account in (you'll need to re-enter your AirVPN credentials)
try again a connection
Kind regards
