Issues getting Connection between VPS / Router about openmptcprouter

[Ysurac]

Did you reboot VPS after install ?
Why do you set a VPN ?

[vinc32]

reboot done - same issue.

I've thought that the ISP (Telekom 5G Germany) may blocks MPTCP Connections - as workaround it said to activate it ;)

[Ysurac]

Even we MPTCP blocked, it should be able to contact VPS API.
What is the result when you go with a browser to https://:65500/ ? and using curl -k https://<vpsip>:65500/ from the router via SSH ? and curl -k https://127.0.0.1:65500/ from the VPS ?
If no results, what is the result of journalctl -u omr-admin from the VPS ?

[vinc32]

browser to https://:65500/

• Nothing - not able to open a connection - not to localhost or ip of router / vps

curl -k https://127.0.0.1:65500/ from VPS

(curl: (7) Failed to connect to 127.0.0.1 port 65500 after 0 ms: Couldn't connect to server

curl -k https://:65500/ from Router

Can you run apt-get install dnsutils && systemctl omr-admin on the VPS ? At least this fix the dig error.
You are using an IPv4 server IP ?
You remove the VPN on 5G interface ?

[vinc32]

systemctl omr-admin -> wasn't found -> not sure how to fix it
"E: Unable to locate package omr-admin"

Using IPv4 Server IP
Removed VPN on 5G Interface

Just went through install routine and noticed something - VPS running Debian 11 with IONOS Image - used
"wget -O - https://www.openmptcprouter.com/server/debian-x86_64.sh | sh"

To install VPS. Maybe that's the issue?

[Ysurac]

Sorry it's systemctl restart omr-admin
I have some IONOS VPS and it's working.

[vinc32]

Tried - but nothing except OMR-Admin changed.

What do you have now in "Status->System log" ?
Range 65000-65535 in TCP and UDP, and ICMP are correctly open in Ionos interface ?

[vinc32]

Added Ports according Wiki, will try to open everything between 65000-65535

[Ysurac]

There is a problem in this log: interface name omrvon, ompn,... ? tunO, tuno ?
You modified it manually ?

[vinc32]

not onsite - so copied out of VMware console - so it copied out of a "picture"

[vinc32]

Solution found -

5G Router has been the issue - it’s a ZTE MC801A and it’s making the trouble.
Changing the APN manually worked.

solution found because I’ve WiFi calling issues inbound behind another one of the same model. Searched for issue and got the hint on sophos forum.

[Ysurac]

Thanks for the feedback
