HTTP/1.1 500 Internal Server Error

[Superpuppy]

I have ICam working with:
3x Foscam FI9821W
1x Sharx Security SCNC3905
1x Old D-Link 6620G
1x Old Logitech USB Cam

Everything works fine except two of the three Foscam cameras I get a HTTP/1.1 500 Internal Server Error underneath where I should be seeing the video.

All three Foscam cameras have the same login/password, and they are one number apart from each other with the IP:Port address.
I have repeatedly copied and pasted the URL in my ICamSource from the working Foscam to the non working ones, only correcting the IP:Port to match the other cameras.
I quadrupled checked the login/passwords on the non working cameras

I am able to log into all three Foscam cameras locally and from remote computers and view videos from all three cameras.

What seems to be the problem here?
Thank you

Do you see that error if you put those exact URLs into a web browser?

Please email a screenshot of iCamSource showing the settings for one of the cameras that doesn’t work to support@skjm.com so we can verify the settings.
