[Staff 9973]

Hello and thank you for your choice!

Please make sure that you're running Eddie 2.19.7 or higher version (upgrade if necessary).

Then, please try the following settings:

• from Eddie's main window select "Preferences" > "Advanced"
• de-tick "Check if the VPN tunnel works"
• click "Save"
• from Eddie's main window select "Preferences" > "DNS"
• de-tick "Check Air VPN DNS"
• click "Save"
• from Eddie's main window enable Network Lock

Try again connections to various servers.

Explanation of the issue: consider that AirVPN uses mainly LetsEncrypt certificates. Then read here:
https://blog.germancoding.com/2021/04/16/lets-encrypt-and-expired-root-certificates/

Now, if you run a cURL version linked against OpenSSL 1.1.0 or older versions, or against LibreSSL older than 3.2.0, or GnuTLS older than 3.6.7, the validation chain will fail (and Eddie does use libcurl and curl). It's a TLS library bug. At the moment we can not fix on our side: we would cut out all Android versions older than 7.1, and we don't want to do so .

Momentarily, the above quick fix will resolve the problem on Eddie. The initial checks become useless when you keep Network Lock enabled, so you don't have to worry about safety and security.

Kind regards
