Proxy error

[Angelo A. Salatino]

Hello all,

I have installed a GROBID client on my server. It was working perfectly until 2 days ago.

Since I am in development phase, I am testing always the same bunch of papers. Up to two days ago, GROBID would classify them, without problem. Now, I get always the same error to the very same papers.

From the web interface, I get:

Error encountered while requesting the server.
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /grobid-test/api/processHeaderDocument.

Reason: Error reading from remote server

To see whether the GROBID instance I am using is corrupted, I installed a second instance of GROBID on a second server (much powerful of the first one) and still I cannot get away with it. Actually, here the process seems stuck and does not return any error message.

For the sake of test, I tried also this client: https://cloud.science-miner.com/grobid/, but I get:

Error encountered while requesting the server.
{ "message":"The upstream server is timing out" }

Ho can I fix this?

I just want to add further details, so you can reproduce the error.

I go to the web page of GROBID http://localhost:8070
Then, I go to TEI,
Then, Process Header Document
Then, I check Consolidate header (only)
Load the pdf
And hit Submit.

I realised I posted it on the python client. I am closing it and posting it on the actual grobid repo
