QGIS not loads a layer from Geoserver WFS

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

Reason:

At geoserver log file, ‘wraper’, I can read:
