LoTW freezes

[ik3umt]

10 qsos are uploaded ok
20 or more upload freezes (I didn't try where the limit is , 11 rather than 19...)
I enabled log tracing but nothing seems involved.
Attached is a side by side log of failed and successful operation.
Of course the LOG4OM generated adif file (also one with 1000+ qso) is correctly loaded when using TQSL program manually.
Any suggestion ?

LOTW has only just come back on line after a major intervention by hackers and there are reports of continuing issues so perhaps wait a week and try again?

Also, the LotW team has implemented a new "feature" that should prevent users to upload duplicates:
We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected.

Maybe this has something to do with it, I had the same issues.
Also the shutdown of Log4OM took a long time and the QSOs were not uploaded to LotW allthough I did not change anything in the settings but it seems that this works again now.

No problem to wait , but I think the problem resides on Log4om, it's a ten against twenty records making difference ? , and no LoTW errors back , it simply freezes.
Again , another 3K records adif uploaded with TQSL gives no issues.
