Once upon a time every thing was OK but suddenly without changing any settings many errors happened


when I try to login to Sentora web mail roundcube I got that error

Invalid request! No data was saved

then when I try to login to Sentora panel I got that error

Application Error: [0204] - The form you attempted to submit had an invalid token!

and cant send or receive emails on Gmail through ports 25 and 110
I also use Webmin and checked emails log and found that error for emails sent from wordpress to my email

Deferred: Connection refused by mail.mydomain.com

I use the default theme
tried to delete browser cache and also tried another browser
I also stopped my server firewall and tried to send or receive email but nothing changed
tried also to reboot my serverI already searched for a solution but found nothing helpful
What shall I do? and why could all this happen?
Help Please

clear the cookie first.

Notice that you have different issues:

1. Login to the panel ( cookies issue/session).

2. Email delivery wich relats to ip being black listed or port 25 blocked.

I haven't seen this before so I checked Google. From the few posts I did check out, it has to do with sessions. Which also explains the 'Invalid token' error from the panel login. Digging some more on why you would have session issues.

Are you using SSL?

About the email sending/receiving.. as Me.B mentioned, did you get blacklisted?

[keem]

I know that they are different issues but why concurrent?
I already cleared cache/cookies ,stopped Firewall and checked if IP is blacklisted
Everything was working normally before yesterday and i didn't do any modifications
I will lose my mind

You can't sort this if you go in all direction.

So step by step and one issue at once. For panel login, check if you don't have your own antivirus causing issues, try using another PC.

And again over SMTP check port 25 not blocked and more logs to see why email deffered.

@TGates :no i don't use ssl
@Me.B I tried logging using another PC with the same error
and when I check port 25 using mxtoolbox.com the result is refused (RST) not open or closed like other ports
so what to do?
I'm really sorry for any disturbance

I solved the email problem by using third-party server using MX records
Now my problem is session security and tokens
any suggestions?

[Me.B]

Do you have custom setup on your server? APC cache ? Anything modified?
