Why might a server fail a test to itself?

updated to last OttoFMS and OttoDeploy

so this is weird if you test the connection before deployment

Well that is strange. Are you using a hostname that the server might not have access to? thats the only reason I can really think this would happen.

No it has a FQDN and a proper SSL, and this copy of OttoDeploy is on that actual server…
TBF it is version next - that might be relevant… In small writing it ays its a 401 error

If its a 401 you might have the wrong API Key in OttoDeploy?
