It appears that there is a space (" ") before the path, please try removing it from the makelibrray command. How did you create the command, manually or using the "Schedule librray update" feature?
The scripts were created in 2017 and use the RadioBOSS API.
wget -qO- "http://newmaster:9000/?pass=xxxxxx&cmd=makelibrary+ZZ_SFNL.xml
as an example. Each of our folders have their own scripts, and each runs via another batch file that calls the API at 1am. The reason it's done this way is so our master system does all the processing and we push the database changes to the studios via our own custom methods.
I quit out of 18.104.22.168, installed 22.214.171.124, ran the script. No errors (version_126.96.36.199.jpg).
Installed 188.8.131.52 again, ran the script, now errors show up (version_184.108.40.206.jpg).
If I need to amend my scripts that's okay, but I'll need to know what's changed between the two versions, for there to suddenly be errors accessing the folder. There's been no system changes in the 5 minutes running between the versions to show the issue.
