Description:
ProtonMail Bridge was not able to establish a secure connection to Proton
servers due to a TLS certificate error. This means your connection may
potentially be insecure and susceptible to monitoring by third parties.

Recommendation:
* If you trust your network operator, you can continue to use ProtonMail
  as usual.
* If you don't trust your network operator, reconnect to ProtonMail over a VPN
  (such as ProtonVPN) which encrypts your Internet connection, or use
  a different network to access ProtonMail.
