Hangs at checking mail server capabilities
Using the Protonmail bridge I am expecting a prompt to accept the self signed cert but I never get the prompt and Thunderbird just hangs with the message 'checking mail server capabilities'. I have set this up many times before without issue but when doing it today on a new PC with a fresh install of everything and the latest version of Thunderbird(78.0.1) it never prompts to accept the self signed cert.
See step 5 of the guide for reference to what I am talking about. https://protonmail.com/bridge/thunderbird#5
