Using rc to change arguments in mount

I am trying to adjust the cache-tmp-wait-time to be shorter without ending my current mount process. Is there a way to adjust it with rc? I tried to do rclone rc list --url http://localhost:12345/ but get this error
Failed to rc: failed to list: failed to decode JSON: json: cannot unmarshal number into Go value of type rc.Params
I tried that with the latest beta (currently running the mount, different path than stable) and stable.
I’m not sure if my rc is wrong since plex_autoscan ran just fine before on these settings

TZ=America/Timezone /user/bin/rclone mount gmedia: /gmedia \
        --config=/rclone/rclone.conf \
        --dir-cache-time=160h \
        --cache-db-path=/path/.cache/rclone \
        --cache-chunk-path /home/user/.cache/rclone \
        --cache-chunk-size=50M \
        --cache-info-age=168h \
        --cache-workers=8 \
        --cache-tmp-upload-path /home/user/.tmp/rclone-up \
        --cache-tmp-wait-time 6h \
        --buffer-size 0M \
        --umask 002 \
        --rc \
        --rc-addr localhost:12345 \
        --rc-user=username \
        --rc-pass=mypassword \
        --log-level INFO \

I don’t think so at the moment.

There are up to date docs for the latest beta here:

If you just want to see the help use rclone rc --url http://localhost:12345/.

(I’ve just realised there is a mistake in the docs. about this…)

I see what the problem is here… you need to supply the username and password in the url, eg --url http://username:password@localhost:12345/
