Appstore not loading

[Colug0]

When I log in with admin creds in my SignalK Server and navigate to the "Appstore", only an empty list is displayed (selected "All" and nothing in the search field). Also If I click on "Server -> Update" the following message is displayed: "Waiting for App Store data to load..."

I tried to restart the SignalK Server and the Raspberry Pi 4, on which the SignalK Server runs. SignalK was installed via Openplotter.

I am looking for ideas on what I could check/do.

The app store data is coming from npmjs.com, more specifically from the api https://registry.npmjs.org/-/v1/search?size=250&text=keywords:signalk-webapp (for webapps). You can try loading that url from your boat to check basis connectivity to npmjs.

The api is accessed from the Signal K server, so even if you can connect to this for example from your phone or tablet on the boat network the server may not be able to do so. Using a browser or for example curl running on the same machine as the server give the definitive answer for connectivity.

People have reported that restarting their linux installation has fixed their app store related problems.

Reports of app store loading problems have been increasing lately. We could tweak the way the app store data is loaded, eagerly and periodically but on demand when the app store is loaded, but there is no really good strategy here. Sometimes people want the module that was just released, and with cached data the update won't be there.

I have the same issue. Basis connectivity to npmjs with no issues.
Looking for solutions. Thx.

EAI_AGAIN means that dns lookup is failing for registry.npmjs.org on your server.

When you say Basis connectivity to npmjs with no issues how did you check that? Did you try to restart sk server or the machine where it is running?
