I rebooted a few times and wouldnt work, soft reboot, unplugged power.
No idea if this makes a difference, but:
I migrates from ISY994 to Polisy PRO. saved a backup of the ISY994 settings.
Migrated everything over (including the Portal access) to the Polisy.
Portal working fine
I had a old broken PLM just refurbed/repaired by INSTEON, and wanted to use the newly repaired on, but was waiting for my serial/adapter cables to come in. During this time, I had to do a reflash of my Polisy OS, which was no issues, and was able to update to most up to date Polisy OS and ISY version. (still have portal access)
I finally got my cables and figured out the proper pin out etc. (had to go with the adapter. I didnt terminate the unused cables at the time). Got the insteon PLM to work (refurb one). That's when I noticed the portal was no longer connected.
Multiple resets and revoking access etc, I was still getting the error: bad request.
THis morning I decided to give it another go. took that DB9 RJ45 adapter and terminated the unused cable with some electric tape. Rebooted Polisy, but decided to use the old PLM that my ISY was using (it's actually newer than the repaired one, dont know if it makes a difference (repaired V2.2 2413s vs a factory V2.4 2413s).
Eitherway. its back on.
THanks everyone for the help!
