ID error while uploading a world

Hello ! I searched for 2 days so far for a solution to my problem... I have a server on aternos and I try to upload maps, but randomly, I get error messages (ID 105 and 198) while uploading.

- I tried to upload on chrome Firefox and Microsoft edge

- I use maps that I already have opened with a client to get the datapack folder and fill it

- I never had connection interruptions

- somehow I get an error message when I'm downloading something on the same browser

- I tried to upload compressed zip files and normal files

- the upload is always very very slow, and the error happens 10 mins after having started it.

Please help ;-;

OK sorry for being A BIT late, i tried that option and it can only upload maps under 200 MB sooo it's a bit bland for my appetite of huge maps. maybe it is only the size of the map that is ruining the whole upload ?

EDIT : i tried, and it seems to work perfectly, except it's very slow. is that normal, or is this problem just a problem of bad connection ? x)

Also ! if you know the type of error that is ID 105 and ID 198, it could help me understand the problem o/
