Is it because Theia has a limit on the size of uploaded files，When I right-click upload, the words “uploading file” only appears for a moment, then disappears, and of course, the file upload failed.but if it’s a small file,after the words “uploading file”,it’ll success
@goth thank you for the discussion
Do you see any error logs in the console when the upload failure happens?
How big is the directory you are trying to upload? (When testing I was able to upload a 10gb file).
Now it’s back to normal, but thank you for replying to me
