Checking for update takes long time

[ghost]

Sometimes when I open ProtonVPN, and go to About to check for update it takes up a long time and still doesn't shows up the if the update is available or not.

Mostly it shows up the information , but a few times, it takes much longer time.

Versions: ProtonVPN 1.20.4, Windows 10 20H2 (10.0.19042.746)

Thank you in advance.
