Bug report

Describe your environment

• Device: Surface Pro 4 (running the linux-surface kernel)
• OS name and version: Pop!_OS 22.04
• IVPN app version: 3.14.17

Describe the problem

I cannot sign into my IVPN account, after not using IVPN and not having IVPN service time for almost one year.

Steps to reproduce:

1. Do not use IVPN for a while, and then pay for more IVPN service time within the last week.
2. Try to log into IVPN.
3. Receive an error about not being able to verify a TLS certificate.

Observed Results:

• What happened? This could be a description, log output, etc.

I saw an error message pop up that stated the following:

Failed to login

API request failed: unable to access IVPN API server: Post "https://api.ivpn.net/v4/session/new": tls: failed to verify certificate x509: certificate signed by unknown entity

Expected Results:

• What did you expect to happen?

I expected to log into my IVPN normally.

Relevant Code (or screenshot in this case):

I'm not sure what happened, but apparently must've been really old configuration files or something (as I saw similar errors when updating the system via APT). I simply removed and then purged ($ sudo apt purge ivpn ivpn-ui), and then reinstalled the IVPN GUI using the Ubuntu instructions. After that, IVPN worked again.
