Inability to access the personal area in QGIS Cloud

For several months I have been unable to access my area in QGIS Cloud to update the changes in the meantime made to the desktop version, also to the map in QGIS Cloud that I created at the time (which still continues to be usable to the July version) .
These are the latest versions that I use, having also tried without result with the previous ones:

QGIS 3.10
QGIS Cloud plugin 3.1.2
Python 3.8
OSX 10.15.1

Logging in, I receive the following error message:
