Request for 'confirmed' role

Hi,

I am a newbie (Drupal user for a few years now but first time I build a site on my own) with a big update issue (see https://www.drupal.org/node/3054547), and for some reason, I can't post a comment on my own issue without it being rejected :

"There was a problem with your form submission. Please wait XXX seconds and try again.".

It's been two days since I tried to post my comments with no success at all!
As some people have answered and need more information, it is really frustrating and unproductive not to be able to reply at all… so I request to get the confirmed role to help me fix my issue,

Thanks for your understanding.
