Authentication fails on multipart/form-data POSTs above ~2.5Mb

[janicetr]

Every time I try to upload a file larger than ~2.5Mb to my webapp, websspi logs the following error message and stops execution:

2023/06/05 11:31:51 Authenticating request to ...
2023/06/05 11:31:51 Authentication failed with error: could not get auth data: the Authorization header is not provided

With smaller files, it works prefectly.

@janicetr hope all is well. I get a similar problem with another ntlm library, except the file size limit is even smaller around 0.7Mb. Wondering if you were able to find out more about the issue and can share what you found.
