OVPN Connect from S10 - disconnects immed now!

info4tim

Hey folks,
For months (up till ~3 months ago) I connected from my S10 via Verizon LTE to my OVPN server with no problems. Now, it Immediately disconnects and keeps trying to no avail. It says "Waiting For Server". Any ideas?

Here's my Connect log file:

It means the server (the pi) cannot be reached.

Check port forwards and firewall.
Does it ever connect?

info4tim

Thx for reply. Not for last sev months. Keeps reconnecting/disconnecting. Did Nothing to any setting.

Pippin

Does it work from another network, not LTE?
Or a different device?

info4tim

Negative. Should I see the attempt in the fios router log?

Pippin

No, your rpi vpn log.

info4tim

Ok when get back home this eve. So wouldn't get any entries in router log then.

info4tim

On the pi, here's the /var/log/openvpn-status.log file contents:

TITLE OpenVPN 2.4.7 arm-unknown-linux-gnueabihf [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on Feb 20 2019

END

Are there other logs I should peruse? Also attempted to connect from another device on wifi on same network as pi - Droid tablet to no avail.

info4tim

As shown above, pi sees some type of comm, (file is touched at exactly my connect time attempt) but no info?
Anyone have an idea?
Thanks

How, on this site does it appear that "folks in the know" respond to a person's request for assistance and lead them along to a point, then Poof...they're Gone!? No further updates, thus dropping the entire effort !!? Seen it over and over here. If you're not going to continue the troubleshooting ahy waste both of our times!!? Amazing

It's hard to get frustration under control and move on to read the howto and manual to discover we get frustrated once again because we lack some basic knowledge.
Let's blame the free support we get from volunteers.....

Read it ^^^!

Maybe Verizon LTE changed something about their network, your phone got an update, you changed some setting you forgot about...

Add

log /var/log/openvpn.txt
verb 4

to your server config and restart.

info4tim

Yay! That's all I needed! As we all are well aware, there are no stupid questions in tech....only the ones we dont ask. We all come here for help since you are the "experts" putting yourself out there to assist. With no reply after a string of Q&As one can only assume you either A, you just dont know anything further, or B, you cant get past your arrogance for folks less informed than you. Which was it?

Pippin

What you needed was https://forums.openvpn.net/viewtopic.php?t=22603 and then the server log @ verb 4

info4tim

Anyone else have any ideas on this ?
