Answer 1

Your QGIS 3.4 is too old. That plugin will only work in QGIS >= 3.6.

The error is:

AttributeError: 'QgsNetworkAccessManager' object has no attribute 'setTimeout'

The setTimeout method was added to QgsNetworkAccessManager in QGIS 3.6.

You can download the latest stable release 3.28 or the most up to date point release 3.32 from download.qgis.org.
