Mx1.mxroute.com timed out

Hi,

I am using thunderbird and last 1 hr i get the following error when i try to send emails (Sending of the message failed.
The message could not be sent because the connection to Outgoing server (SMTP) mx1.mxroute.com timed out. Try again.)

Please advise if you have similar issue and you found a solution

Apologies, some trouble with the SSL certificate expiring, and an excess of manual actions taken to set it up in the first place, led to an issue that took longer than intended to correct for SSL connections to IMAP/SMTP. MX1 will be receiving an upgrade soon that will ensure this does not happen again.
