What would cause FQDN connection to fail?

TommyKL

Sorry, not enough space in the title to explain.

I have an ovpn server (2.4) running that handles a few connections from remote users.
It has a FQDN DNS entry. It can be pinged from anywhere so we know the issue is not DNS.
When users connect to the vpn server, sometimes the name doesn't work and they have to use the IP.

For example
www.domain.com:8080 (for some service on port 8080 for example)
www.domain.com:8081 (for some service on port 8081 for example)

This seems to be a hit and miss. One minute it works, then the next they have to use the IP.
1.2.3.4:8080 (for some service on port 8080 for example)
1.2.3.4:8081 (for some service on port 8081 for example)

What could cause this kind of error? I'm not sure what information to provide but happy to share.

No you don't .. all you know is that you can ping a name.

TommyKL

Ok, fair enough. Can you expand on that.

I can add that the public DNS name is different from the internal LAN DNS / hostname name. Could that be one reason?
The public DNS name is (example) vpn.domain.com while the internal DNS is vpn01.different-domain.local.

So terse, no friendlyness what so ever or you have no clue so taking the easy way out.
Your link to help doesn't help at all. What makes you think I didn't read my butt off before asking in forums?
What a strange way to treat people. What's happened to this project? I'll find my help somewhere else.

Openvpn relies on your system DNS.

Your system DNS is unspecified and you are using two separate names for the same service.

Also, you don't know how your system works.

If you wanted help here with Openvpn then we need to see your configs and logs.

But google is probably a better place for you to start ..

TommyKL

Ya, I used Google a lot but there is no specific thing to look for which is why I ended up here asking for leads.
You know nothing about what I know or don't know. You like everyone else had to start somewhere. It's too bad you grew up to be so large headed that you cannot even be nice to someone you don't know.

God forbid I ask you to solve this, I would get the endless 'I'm just a volunteer, not your IT person' reply.
I was only looking for leads and I even gave you one.

TinCanTech

It is your system and no doubt some body is paying you to do a job that you don't know how to do ..

If you need professional help then I am available for hire.

TommyKL

Wow, so rude. Just incredible. No thanks, I would never hire someone with such a terrible attitude toward others.
I don't need your 'professional' help. I just want to learn more about this system and have to ask questions now and then.

And yet you refuse to divulge the details of your system......

We are not here to teach you about your DNS solution and your job.

If you want help then go to the right place to ask and if you ask here then provide the details requested.

And I am not rude, I am simply matter-of-fact.

Your question is: What can cause DNS to fail ?

My answer is: What has that got to do with Openvpn ?

For all we know, you are using Free DynDNS and your account has been terminated.

TommyKL

It has everything to do with ovpn because there is nothing wrong with the DNS.
You're not rude??? What a silly joke that is, you cannot even understand how you act.
You've already wasted my question with all this nonsense.

>'we are not here to teach you'

LOL. Famous line used by aggressive people with zero social skills in life, looking for targets in forums.
Enjoy your evening, I'm sure others are just dying to get your welcoming replies too.

TinCanTech

This has nothing to do with openvpn.

You simply do not understand how to do your job.

And then you come here to ask total strangers to do it for you and get upset by our replies.

Go tell your superiors about me and let them read this thread .. if you have the stones.

And FOR THE RECORD:

You called it .. we are all volunteers. I offered my professional help already.

I'll let your boss decide if you are worth the money they are paying you ...
