Server Suddenly closed port

[[MTA]Weed]

I have been running my server for almost 1 year on the same hosting, and since yesterday im having problems with my mta, my port "22126" is closed.

My firewall off, my port open 100%, i check it from diifferent sites, but mta says that the port is closed.

Port 22126 is open on 185.203.119.83

I havent logged inside console in like 7-8 days, and this happend by itself.

Port 22126 UDP is closed. Players can not browse!
Port 22003 UDP is open.
Port 22005 TCP is open.

The problem is one byte UDP packets to 185.203.119.83:22126 are being dropped. Two bytes work, so it must be a router/firewall setting somewhere.

FYI Linux commands to test using a remote machine
Sending "r" fails:

echo -n "r" | nc -u -w1 185.203.119.83 22126 | tr -dc "[:alnum:] "

Sending "rr" works:

echo -n "rr" | nc -u -w1 185.203.119.83 22126 | tr -dc "[:alnum:] "

i test with various websites to check my port example:

Port 22126 is open on 185.203.119.83

 

i will try reinstalling the system, see if problem persist.

The solution is to ask your server hoster to allow 1 byte UDP packets for your server. I expect they recently blocked them due to a DDOS attack on their network.

The hosting said that all ports are open to my server.

Seems to be working now
