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