On my UC300, a similar problem, here's what I found out:
- Error 500 appeared after updating the firmware to version 3.x. Fortunately, it does not appear on all pages (it was noticed, for example, on the PBX/Extensions page). After rolling back to firmware version 2.5.6, the error was resolved.
- It is not possible to connect to UC300 with the putty - an error "Connection refused" (both in telnet mode and in ssh mode).
- Reboot does not help.
- Pop-up messages say that updating from version 2.x to version 3.x needs to be done through version 2.5.7, but there is nowhere to download it.

hi pavel,

you can download the 2.5.7 version from the following link
downloads.openvox.cn/pub/firmwares/IPPBX...k/uc-a01-current.bin
For the latest 4.1.0 version, you can get it from this link.
btw, you need to do the factory reset and config manually after upgrade
