Error 521 only on port 8880



I’m trying to setup something called TcAdmin :

The admin panel using the port 8880, but when i go to it give me the error 521.

Auto-Minify, HTML IS checked, Javascript unchecked and i cleared the cache files.

Can someone help me out ?

Thanks :slight_smile:

#2 is not listening on port 8880. A telnet to the origin IP address results in a connection refused message.


Not my domain :slight_smile: real domain is


I checked, just didn’t want to expose your host name or origin IP. It wasn’t listening when I checked, but appears to be now. :slight_smile:
