Publishing Online : Error #18 / Publication en ligne impossible !

Hello,

Suddenly, I can't publish online anymore.

It's going through 99% then "Error #18".

I tried everything (log out everywhere, resintall, two computers with various Os), no problem with the payment.

I can't publish on my side, but I did a package to a friend and he was totally able to publish with his account.

The problems seems linked to the account, not the files/computer/Os.

Exactly like here :

Do I have to stop my subscription for a new one ? Is it the only solution ???

Screengrabs : first one is a 100 pages, second is totally blank. Same result everywhere. Two other friends were able to publish.

{"_links":{"self":{"href":"https://cc-api-cp.adobe.io/api/v2/limits","type":"application/hal+json"}},"small_file_upload_limit":52428800,"rendition_size_limit":2048,"copy_job_subtasks_limit":1000}

Thank you in advance for your help !

Best regards,

Jean.
