I'm using owslib.wps inside a QGIS plugin to retrieve a pywps query output. Here is a piece of code that I run from the QGIS console:
import owslib.wps
from owslib.wps import WebProcessingService, printInputOutput, monitorExecution
processid = 'tp_np1'
wps = WebProcessingService('http://myhost/wps', verbose=False)
inputs = [("input1", "table01"),
("input2","91")]
execution = wps.execute(processid, inputs)
out = execution.processOutputs[0].data[0]
table_name = out.rsplit('/', 1)[1]
vlayer = QgsVectorLayer(out, table_name, "ogr")
if not vlayer.isValid():
print ("Layer failed to load!")
QgsProject.instance().addMapLayer(vlayer)
iface.showAttributeTable(vlayer)
When I run a long query, I get this error:

Is there a way to set a different timeout value ?
Note : I'm using QGIS Dev 2.99 with python 3.6, but also I'm getting the same error message with QGIS 2.18 and python 2.7
