XF 2.1 Zend\Mail\Protocol\Exception\RuntimeException: Unsubscribe connection error: read failed - connection closed?

[Serpius]

Users are not able to log onto the website at all, so I checked the server logs and this is what I found.

Could this be blocking the users from registering on the website?

Yes, I already have uploaded all of the files (3 times already), which I got a few days ago when I bought my new Xenforo software.

How can I fix this? Please be specific as I am new to Xenforo.

Can anyone help??

This is blocking new user registrations and I'm getting emails regarding this issue and I do not know how to fix this.

For the email issue, you will need to contact your host as it indicates a server level problem.

That's weird. I just did that yesterday from Google Captcha. I guess I will re-do that again.

UPDATE: For some odd reason, Google Captcha told me that the keys were not valid. WTF??

Whatever, I re-did it again and hopefully, it will work this time.
