I was also getting the “no route to host” message. I changed the Network to NAT and that allowed me to access the login dialogue.
However, I cannot log in successfully. I have three different SMB accounts on the ZimaCube and none of them are working.
My main account mounts all of the ZimaCube’s subfolders, and if I go into /media I can find my hard drives, NVME, and RAID. But I cannot access the RAID, only the NVME and hard drives. Very strange.
The other two accounts require me to login once, then enter the account password a second time, then says “You don’t have permissions.” Even though I created the third account specifically for Ubuntu, to access only the RAID.
Note, in the Ubuntu Files app there is an option for “ZimaCube (File Sharing)” and “ZimaCube (Remote Login).” Only the Remote Login option allows me to enter account details. The File Sharing option doesn’t load anything. (In the toolbar it says it was looking for Windows Shares, which should be the SMB?)
When I delete the password in the Password Manager to try again, I also noticed it’s trying to use sftp:// for the login. Not sure if that’s right or wrong. Technically it works to load the subfolders when using my main account, but not the RAID.
What am I missing? I saw that 1.5.4 introduced and SMB bug, could it be related?
