Manga list update issue

[bofantinico-cloud]

Hello,

Looking for french scan, I have several source that can not have the manga list updated, I got this pop-up for example:
SushiScan Manga List: 404 Not Found

Checking the website and no issue.

Can I try to update the source somewhere in the soft?
I have the issue for Sushiscan, MangaToonFR.

Thanks
