Apologies if this should have been in a different forum!
I run OMV and have the Duplicati plugin installed to back some of my files up to a cloud storage provider. Yesterday I updated my OMV installation through "Update management" in the web interface. After this was completed, I went to check if Duplicati had any issues and it reported an update being available. It didn't immediately click with me that this was originally installed through OMV (I run it elsewhere, too) and so I clicked to update.
Now, when I try to access the Duplicati web interface, I get the message:
"The host header sent by the client is not allowed"
I guess I could start digging around in this and see how I can get it all fixed, but I am worried I'll worsen the situation by trying to fix something that was installed by and is (sort of?) being managed by OMV.
Any pointers or suggestions would be helpful!
