Error in submitting add-on

[dogincbagel]

I am getting this error when trying to upload my zip file containing my add-on

https://addons.thunderbird.net/en-us/developers/addon/submit/upload-listed
https://addons.thunderbird.net/en-us/developers/addon/submit/distribution

It has been happening for days and in different environment connections.

I get the same error when selecting distirbution "on this site" and "on your own"
