Dude 3.1 new installation

Hello,

I just instaled Mikrotik 3.17 and Dude 3.1 on Pentium II 233 - box only for dude. (DOM 1G).

I added to NetworkMap many devices (~140), only core routers, all on RouterOS.
When is uninstalled second ethernet card, I lost NetworkMap - is empty!

Devices and monitored services still are in dude.

How get back NetworkMap?

regards
patt

I upgraded my hardware to IBM x305 (P4 2,4GHz, 1G RAM)
MT on DOM 256M dude storage on HD 6G.

Server dude rebooting sometimes, access via www (port 81) not working - empty page with connection error.

always export configuration before doing any major change, like hardware upgrade

Yes, I did.
Dude is working (as You see in another topics) but www access on dude@routeros not.
www access working, when dude server is located on windows box.

regards
