Did you add a unit to Melcloud, what kind of unit is Salon?

[JPGNT]

My equipment has not changed since it was installed. The "Salon" unit is an MSZ-SF42. Everything was OK for 2 years. The problems appeared after upgrading Domoticz to v22020.1 (now I'm in v2020.2) on a Synology DS218+ NAS
Thank's for your help.
