Synology Docker, Plex update site is down

[EVOTk]

Server Version#: 1.13.9.5456
Player Version#: 3.89.2

Hello,
Since my transition from DS3615 to DS918 + plex does not update. Do you know why ?
Thx

I solved the problem here is the approach:

Save your config (in container, export on Plex)

Delete it in container, then also delete the image in “Image” and re-upload it to “Registry” by searching for “linuxserver / plex”

Then reload his config in “Container” by doing “Import”
