Remote host closed connection during handshake

bondicoffee

Hi,

While connecting to an incoming email, the server is throwing an exception -- 'Remote host closed connection during handshake' for outlook 365 email account.

On restarting awareIM, it starts working and throws this exception after some time.

Has anyone noticed this exception in AwareIM and is there any fix that can be applied?

Thanks!

Not sure what this is but I have had various issues and possibly also handshake issues when my host made changes to their email servers so one thing you can try is to change the ports used and always make sure you use SSL ports.

Hi,

Thank you for your reply.

We are using port 8443 as SSL port. Following is error received on tomcat logs:
