[GeoNetwork-users] 502 Error when checking prerequisites for DOI assignment

Hello,

I have just installed Geonetwork (v. 3.12.6) and I have a problem with DOI assignment.

The problem occurs when I do the verification of the prerequisites. If the metadata sheet doesn't have all of them, I get an error message with the missing prerequisites listed. On the other hand, if the metadata sheet is correctly completed, the verification does not succeed : I get HTTP 502 error (Bad gateway / proxy error).

If I look into the Geonetwork logs, I get this error:

I have looked for resolutions of similar cases but I haven't found anything, do you have any clue?

Thanks in advance,

Davien
