QGIS not loads a layer from Geoserver WFS

Question

This is my geoserver http://webservice.dftrans.df.gov.br:8080/geoserver/web/. It is active. You can get data using wfs services.

Up to 3 weeks ago I could use QGIS and add wfs layers from my geoserver (http://webservice.dftrans.df.gov.br:8080/geoserver/web/). Now, I can't get layers from it.

I connect to WFS server, I can see the layers, but when I try to load a layer, after timeout, I read this WFS message in my QGIS display:

Network panel:

WARNING    Network request http://webservice.dftrans.df.gov.br:8080/geoserver/wfs?SERVICE=WFS&REQUEST=DescribeFeatureType&VERSION=2.0.0&TYPENAMES=DFTrans:Camada_de_Pontos_de_Rede&TYPENAME=DFTrans:Camada_de_Pontos_de_Rede timed out

WFS panel:

Reason:

At geoserver log file, 'wraper', I can read:

What I must do?

Answer 1

Your GetCapabilities response is broken:

error on line 6119 at column 56: Unescaped '<' not allowed in attributes values

Looking at the response it seems that you do not have a generic.sld for layer opc_postos_sba - so there seems to have been some corruption of your data directory. This can be fixed by going to that layer and changing it's style to one of point, line or polygon, or by restoring the generic.sld file from your backup.

You should probably also upgrade as 2.8 is a very old version of GeoServer (now working on 2.19).

Answer 2

Without specifically addressing your problem, often when having issues with a particular layer in Geoserver, recreating/republishing the layer from scratch (ie: Start again) often resolved any issues I have had in the past.
