Observer Hermeses Call Fail (Failed to get Hermes URL from Blockchain) error in log

[theVasilis]

Describe the bug
The node won't start because in every restart attempt the process fails with the below error message:

observer Hermeses call failed, using fallback known hermeses...

and then on the next line of the log:

failed to get Hermes URL from blockchain, using fallback...

further down:

Failed to execute command: error="could not get Hermes URL:....
Main process exited, code=exited, status=1/FAILURE
Failed with result exit-code

and then mysterium-node-service restarts and attempts the connection again.

The service is running fine systemctl status = ACTIVE, ENABLED

One thing I've noticed by checking the files is that the file config-mainet.toml is empty (or I can't read it with cat or nano). I believe there should be some configuration data there and that might be the reason of this error.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
I expected Myst Node to complete the online connection and bring me to the NODE UI or at least show me a success message with a NODE ID. (I'm running SSH in terminal mode.)

Screenshots

Environment (please complete the following information):

• Node version: Latest one (just installed it 12 hours ago)
• OS: Debian 12 Bookworm on a VPS
• CPU: Low MHZ entry-level VPS (but running ATOR node perfectly)
• RAM: 1GB
• Desktop app version (if applicable): Terminal
• Docker (if applicable): N/A
• Your identity (if applicable): N/A (didn't manage to reach at this point) [from the back office zeXB4nlubbFkq8954Th1uc5pG5wY4qJuYw5Ocqs6]
• Payment (top-op) reference (if applicable): N/A

Additional context
After using the script to install the node, the service was stale because the firewall was blocking all connections. I reviewed the logs and identified the ports Mysterium Node is using, so I proceeded and whitelisted them. Then restarted the service and since then it is ACTIVE and ENABLED and it automatically restarts for 5 times.

Just to add some updates.

I managed to claim my node on the dashboard and I can visit my node's public URL.

Now it appears to be Online with Enabled Monitoring, Quality High and NAT Open indications.

Here's the node's ID: 0x0b873d7c7f673a704e8a858707e1ca33a758a4bc

It seems that it is already serving traffic and users, so I'm not sure if that issue is still relevant.

Please feel free to close this issue if it irrelevant.

I think I have same issue with my RPi. How did you completely solved that problem?

I think I have same issue with my RPi. How did you completely solved that problem?

@Teense my Debian installation didn't have any hostname added under /hosts.conf file. It was completely empty, so I added the default Google and CloudFlare hostnames (8.8.8.8, 8.8.4.4, 1.1.1.1) and then the node appeared to be connected and operating online.

Now i'm not sure that is the solution, because I have the Debian installation set to auto updates, so it might be some library receiving updates overnight.

I hope that helps.
