WebServer:8080 thread seems to have ended unexpectedly

Hello,
I currently upgraded from 2023.1 to 2024.4 because problems with Python & Paho MQTT.
Some of them are resolved but not this one :

Code: Select all

import sys
sys.path.append('/usr/local/lib/python3.9/dist-packages/')
import DomoticzEvents as DE # voir https://www.domoticz.com/wiki/Python_Events
import requests # https://fr.python-requests.org/en/latest/user/quickstart.html
from requests.auth import HTTPBasicAuth
from paho.mqtt import client as mqtt

Broker = "192.168.0.45"
PortaBroker = 11883
KeepAliveBroker = 60
clientID = "Boggiz"

CodePG = DE.user_variables["NewCodePG"]

if DE.changed_device_name == "Test Python" and DE.Devices["Test Python"].n_value_string == "On":
client = mqtt.Client(clientID) #create new instance

rc= client.connect(Broker,PortaBroker,KeepAliveBroker) #connect to broker
if  rc != 0: print("[E-STATUS] Connection au Broker. Resultat de la Connection: " + str(rc))

if CodePG == '' : CodePG = 'Re-Init'  # si ESP recoit ce message il renverra un nouveau code sans ouvrir la porte!

client.publish("home/domoticz/PG/Dz2PG", CodePG, qos=0, retain=False)    #publish message

# initialisation de la User Variable avant reception du nouveau code
url= "http://192.168.0.45:18080/json.htm?type=command&param=updateuservariable&vname=NewCodePG&vtype=string&vvalue=" 
CLE64 = {"Authorization" : "Basic RG9tb0JvZ2dpejpEUyFhZnMhYWZ5MTk1MA=="}
rc = requests.get(url, headers= CLE64)
if rc != 0: print("[E-INIT User Variable] erreur: " + str(rc))

This code works fine, the user variable is correctly initialized but a minute later, Domoticz froze with the error above (title).
An idea ?

Hello all,
I am partially answering myself.
By adding 'timeout=5' in requests.get Domoticz no longer crashes but I have a long list of errors in the log:

How to avoid these errors ?

... it's very easy with TRY exceptions !
