When I connect the Dwarf to my mac via usb sometimes the connection doesn’t work.
I don’t know why but seems like the mac doesn’t “read” the Dwarf. Usually I reboot the Dwarf, refresh the web UI and everything is fine. Sometimes even rebooting doesn’t work.
Is there a procedure to follow when this happen?

Go to System > Network
Delete the connection “Mod Dwarf”
Unplug USB, then plug in again.
If you just unplug and plug back, there will be 2 Mod Connections. That’s why it won’t connect.

Thanks @QuestionMarc 
@al_bern, did it solve the issue?
Also, please make sure that you have your Dwarf up to date.

I tried this and now when I connect the Dwarf nothing happens in network, no connection, not able to use the GUI. It has worked well for a long time and just started misbehaving. On Mac mini Ventura. Tried all the obvious things like restarting everything and unplugging replugging everything.
Same here. Booted up my computer now, web interface is not working no matter what I do. I’ve had issues before, but rebooting the MOD Dwarf usually works, now I’ve deleted the network connection etc., nothing is working.
I can ping the IP and the moddwarf.local, but that’s all.
Now my unit is fully unresponsive despite restarting it…
Update on this.
I’m on Mac by the way and it’s been working fine up until today.
I have deleted the network connection several times. I’ve rebooted my Mac.
I’ve changed the network system behaivour several times.
I’ve rebooted the Dwarf several times.
I’ve tried both the moddwarf.local and the IP.
I’ve tried different USB ports. Haven’t tried different cables.
I’ve tried both Firefox and Safari.
I have not tried a different computer.
Finally, I decided to just factory reset the device according to wiki/Troubleshooting_Reinstall_Dwarf.
However, this led me into a completely new world of trouble, because the device did not have enough storage space for the reset image.
With my very limited knowledge and some googling, I managed to delete the contents in the pedalboard folder through Terminal (this is not a troubleshooting step stated anywhere, so don’t do this. I took a risk because I’m frustrated).
I finally did the factory reinstall completely.
I still can’t connect to the WebUI.
I’m now at an end’s road with troubleshooting and frankly, my inspiration I had to create some music today is gone. All because of one pedal that doesn’t want to connect to its WebUI.
I would try different cables. That often did it for me. Too bad about the inspiration, although seems you have the lyrics for a song many modern musicians can resonate with 
Tried a different cable, didn’t work.
The pedal connects to my PC without issues.
I’m done troubleshooting for now. I’ve packed up the pedal and feel quite done with it.
Sorry to hear that, and apologies for trying to be funny. I know it`s very frustrating with technical problems. Especially when the Dwarfs potential is so great. I also had some weird beaviours in the past, but it always dissapeared quite fast. I hope you will get help to solve the problem. I am only a Dwarf user and should probably not pretend to offer help even. Good luck!

Has your Mac updated any time recently that would coincide with the connection failures. IIRC, Apple’s network stack had some known issues. Perhaps they “fixed” the issue and now it causes new issues?

No need to apologize for making jokes. I don’t mind.
It’s possible, but the latest update was on the 29th of July from what I can see and I used the pedal 4 days ago without issues.

You are right. I will save this on notes for an update on the wiki.
Do you mean that you can connect it and access the WebGUI on a PC and not on Mac? I’m not sure if I understood it right.
If that’s the case, I would say that the issue is somehow on the Mac side.
Can you try to use Google Chrome or Brave as a browser?
Hey, appreciate you taking the time and responding to me.
It’s important to note that everything worked well up until it didn’t on my Mac. But yes, the WebGUI worked in Firefox on my PC.
I use Firefox on my Mac as well, but tried Safari, none of them worked. I can try Chrome too.
I’ve tried on Google Chrome now as well, still no connection.
For every time I try something new, I also make sure to delete the connection in Network settings to get a fresh start. Nothing seems to work.
The Mac even had a system update today, so I was hopeful it might solve it, alas, it did not.
