I just added more reporting to this function to get closer to that error.

Can you please install the "beta" version 2.0.2 with this command inside your Node-RED folder (normally "~/.node-red")? This is the command for installing it directly from github:
npm i https://github.com/Looking4Cache/node-red-contrib-remote.git

After that, the AggregateError should be exploded to all errors hold inside. Can you please append these errors then?

Here we go:

The exceptions seems to happen once for each remote config node that I have

[Looking4Cache]

I got some questions:

How much time there is from the line containing "[remote-access:Node-Red Dashboard] Sending config to server:"? If its really a timeout, it should be 30 seconds..

After some seconds the access node should try again to connect. Does the error persist then or does it works on the later tries?

[Donni1966]

i have the same error. Reinstall remote, config new - but after setup, reboot node-red i get the same error. Not timeout. it happens directly in the start sprozess.

I also have this error. If I start Node Red in safe mode then deploy, it works fine. If I then change configuration and redeploy, Node Red crashes. When I try to start Node Red with an access node in my active flow, I get the error and Node Red can't start.

@Donni1966 @simcmichael Did you both used version 2.0.1 or did you used the test version 2.0.2 from manual install?

Can you please install the "beta" version 2.0.2 with this command inside your Node-RED folder (normally "~/.node-red")? This is the command for installing it directly from github:
npm i https://github.com/Looking4Cache/node-red-contrib-remote.git

[Donni1966]

i use 2.01 - do no manual installing. have to test this - but i run in a docker so the manual install is al little more tricky.
i will try is next days.
or can wait for the final version.

[Looking4Cache]

@Donni1966 I just released 2.0.2. It will wrap the error so it does not crash Node-RED and does better error reporting.

For me it will be interesting if the Access Node brings an error on startup. And if it works on the next connection try (after some seconds).

[Donni1966]

dam :-) 10 Minutes earlier and i get with the palette update :-D Bit positiv Feedback - is work now aber reboot. For me fine.

good job thanks a l lot. The ist one of my favourite node-red tool :-)

[simcmichael]

Thank you! I still get the error on startup, but it launches now and I can connect.
