The underlying connection was closed

This error pops up regardles of the size which I want to upload to the solution. I don't get this error with any other plugin, only with this one. The full export of the translations icluded 5 Entities with almost all the choices (optionset, fields, forms, dashboard etc.). So when I imported the file, the error occurred at the beginning only 10 attributes in of the importing process. The batch size was set to 10 as default. After some tries I removed some table sheets from the excel and only imported the attributes which had 1007 rows. Again after the first 10 attributes it failed. So I tried a different sheet "global optionset values" which only had 300 rows. It made it to the last row, but failed when it was publishing the customization. What can I do to fix this?

@wd21sos I have the same issue with translations. I have tried multiple ways but eventually this error always occurs. The funny thing is that sometimes part of the translations visible in the solution.

Would be wonderfull if there will be a solution for this issue.

What is the timeout set for the connection you are using? By default, it's two minutes but you can raise it to whatever you want
