Lost cameras after upgrade

Hi guys, I hope someone can offer a solution for my issue. I just upgraded to 6 and I had two cameras stop working after the upgrade. Both initially were showing “Error: ffffffff (Socket error) 0”. After fiddling with one I got I to now say “failed to connect” These are older cameras but they were working and I’d like to get them back. Both are visible when I put the IP into a browser so I think it’s a config error in BI. When I use the Find/Inspect it goes thru but doesn’t make any changes. I tried some settings from similar model cameras but I’m not having any success getting them back online. I deleted one and re-added it, but it still won’t connect. Any suggestions would be appreciated.

I was able to self-rescue. Thanks anyway sir. It's all working now I left the name of the cameras off because I didn't want to get flamed lol. On a side not I just got three new Hik DS-2CD2387G#-LIS2UY cameras with the new ColorVue 3.0 and the night vision performance is impressive. No ghosting in motion with available light.

For some reason the gateway was incorrect on 2. Also, the media/video/RSTP ports and the Discovery/ONVIF ports were wrong. I got into the cam configs with browser t get the correct settings, input those values into BI and re-ran the Find/inspect. That got them back online. Keeping old cameras around is worth it for me because they still work fine and I would be short 4 views without them However I learned a lesson and will not BUY any more cheap cameras. I will certainly use what I have until they die though. I'm still running my original 4 analog cameras as well

Here's a pic of the network rack I built in my woodshop and of my BI box.
