Hello/Hi/Greetings,

I have been very happy with Piwigo and have used it for about 7 years.  I have a few hundred photos on an iPhone which I would like to upload to my Piwigo gallery which I self-host.  When I try, the upload starts, then Mobile App throws the error:

Upload Error
Could not upload your photo.  Error: Request failed:  unacceptable content-type: text/html

I have the Community Plugin functioning. The error occurs with no plugins or with several plugins active.  I have checked my nginx logs, and php-fpm logs.  No help.  Not sure what to try next.  I am using the latest php versions, nginx versions and mysql 8.0.  Server is running on FreeBSD.

Uploading in general works fine to/from a desktop or laptop computer.  Anybody else run into this problem? It would help my user base tremendously to have the Mobile App upload feature working.

Thanks in advance.  Love the product!

Piwigo version: 2.10.1
PHP version: 7.2
MySQL version: 8.0
