Dropbox is configured as our default full server backup method, scheduled daily. The error, Transport error: Extension transport: ext://dropbox-backup/server displayed every time until I installed the panel.ini editor and revised the settings as follows:
[ext-dropbox-backup] ConnectionTimeout 30 90
[ext-dropbox-backup] RequestTimeout 300 600
[ext-dropbox-backup] PauseBetweenAttempts 30 15
After the panel.ini configuration changes, the backup manager now loads (after a long delay as expected) inconsistently. If it does not load, the Transport error: Extension transport displays in red at the top and the latest backup shows as unavailable. If it does load, the latest backup shows as successful, but with the message, "The backup (time/date) was created, although some issues occurred and the backup might not be entirely valid." Upon viewing the log, the error, Failed to exec pmm-ras: Exit code: 129: Transport error: Extension transport: ext://dropbox-backup/server displays.
