Can't connect Laird RG186 gateway to TTN

[calybyte]

Hi guys,

I have bought a new Laird RG186 gateway and I can’t get it to connect to TTN.
Following the guide at Application Note - Setting up Basic station on the Things Stack v3 I did the following steps:

1. Connected the gateway via ethernet, changed my credentials and updated the firmware to the latest version (Laird Linux gatwick-laird-93.9.6.30).
2. Logged in to the TTN console > go to gateways > Register gateway
3. Entered the gateway EUI (C0EE40FFFF2A378C), gateway ID, name, frequency plan (Europe 863-870 MHz (SF9))
4. Not in the manual, but I guess this is necessary: enabled ‘Require authenticated connection’ and enabled ‘generate API key for’ CUPS and LNS.
5. Registered the gateway.
6. Logged in to the gateway again, LoRa > Forwarder, set the mode to ‘Semtech Basics Station’.
7. Set the LNS address to wss://eu1.cloud.thethings.network:8887
8. Uploaded the ISRG Root X1 server certificate file I downloaded from https://letsencrypt.org/certs/isrgrootx1.pem
9. Uploaded the tc.key file that was generated earlier.
10. Pressed the ‘Update’ button.
11. Connection state remains ‘false’ and nothing new in the TTN console, so I rebooted the gateway.
12. Still nothing, so I checked the gateway logs:

I also tried LNS address wss://eu1.cloud.thethings.network:8887/ (with the trailing slash), but still nothing.

Could anyone please help me? Thanks in advance for your help.

The error message in the log says there shouldn’t be a trailing slash …

True, but this message also appears in the logs if I try it without the trailing slash:

I have tried using CUPS instead of LNS, but this also didn’t work.
Then I tried the solution posted here: Can’t get Laird RG1xx Basics Station Forwarder working with TTN - Gateways - The Things Network
Also, no dice. What’s even more strange is that whatever server addresses I use, I always get this error:
2023-01-17 10:49:40.972 [AIO:ERRO] Malformed URI - expecting ws(s)://host:port (no path, port mandatory) but found: wss://eu1.cloud.thethings.network:8887/
I guess I will have to ask Laird for support.

I managed to solve the problem with the help of Laird. For others who might encounter the same issue: there’s a bug in the latest firmware release that might cause corrupt configuration files, preventing the gateway from connecting to a CUPS or LNS server (bug ID 21421). The solution is to factory reset the gateway (power off the gateway, hold the user button and keep holding it while you turn on the gateway, release the button when all LEDs start flashing) and configure it again.
