LSP: Autocomplete in deno.json not working when offline

[marvinhagemeister]

Was somewhere remote the past day where I had no internet connection. I noticed that the LSP isn't able to provide autocompletions in deno.json without an active connection. This is the output from the LSP:

Download https://deno.land/.well-known/deno-import-intellisense.json
  Error fetching registry config for "https://deno.land": Import 'https://deno.land/.well-known/deno-import-intellisense.json' failed: error sending request for url (https://deno.land/.well-known/deno-import-intellisense.json): error trying to connect: dns error: failed to lookup address information: nodename nor servname provided, or not known%
