Update of geocaches' list failed

Hello, I wrote another question which I thought it has been solved

https://help.locusmap.eu/topic/38001-locus-map-4-update-geocaching-list-of-many-caches

But today I cannot refresh list of 750 geocaches again. The progress bar was very slow, stucked at 5% and then the error code was printed. Also refresh of smaller list is significantly slower than before with geocaching4locus plugin (mayby 10x slower).

In Locus Classic with geocaching4locus plugin it takes abount one minute to refresh the same list (PQ of Bratislava district).

My workflow is - download PQ of whole home district every week to separate list and then refresh all the geocache in this list. Now it is completely unusable. I must refresh the geocaches in GSAK or GeoGet via PC and then import updated GPX to Locus, so flow PQ/update directly in Locus 4 menu is not usable for me.

Testing scenario: build the list of many geocaches (16000 is daily limit by Groundspeak for full update) and refresh them or take all Croatia caches from gpx attachment (around 6000) and refresh them all in Locus - update geocaches (with elevation).
