Solved People can't connect to my server (anymore)

Okay, let me explain the situation here. I have private server for friends and events, everything worked fine until my connection decided to kick out my PC from the internet access. I couldn't use that connection for a several days so I had to use a sub-connection, the server already happened to be broken then but I thought it was because of the sub-connection.

Using my main connection now, the server is still broken. I can connect to it with localhost and strangely even my external ip, but others can't. This is the error message they are getting. NOTE: The console doesn't mention a failed connection or some sort.



This is what canyouseeme.org says:



As I already mentioned before I can connect on it through my external ip and the custom ip I am using. This server slot uses the custom ip.



So I have no clue what is happening right now, I already have googled for solution but none seemed to work for me.

If you have any possible solutions, please share them with me. Thanks!

EDIT: When it was offline I updated my server from 1.7 to 1.8 but that doesn't really have any affect on the connection or does it?

 

So the server starts up fine? Can you pastebin a FULL copy of your logs?
Sounds like a network problem?

 

Here you go:

Thanks for offering help!

 

Did you have your computer port-forwarded, if so do it again therefore being the reason others can't join. You could always use hamachi instead, but port-forwarded it again if it was previously.

 

@MatsExe Never use Hamachi, your friends will hate you

I think that your internal IP may have changed. Before the connection loss it may have been 192.168.0.5 and then now it's 192.169.0.6 or something, so check that by lauching command prompt and typing ipconfig. Look for the internet connection type you're using (mine is Ethernet adapter Local Area Connection) and look at the IP for IPv4. Mine is 192.168.0.2, though it was 192.168.0.4 a few weeks ago. Make sure that it matches the portforwarded one.

 

I removed my old port forwarding setting and redid it but no fix unfortunately, I could send you some settings of my port forwards if that clears up something...

@oceantheskatr Actually my internal ip did change but that didn't fix the problem when I tried to re-portforward it.

 

Solved.
If some people experience the same issue:

Removing the external IP from my port forward settings removed the thing where I could strangely connect with the public IP but others couldn't.
I restarted my router and used a DMZ host, which seemed to work.
