Can't change default pool data using browser interface or in bmminer.conf???

[Moria843]

Have an 8.5 Th/s R4. When I try to change the pool URL from the default antminer pools and hit Save&Apply all fields go blank and doesn't connect to anything.

Can do the R4 reset button and antminer pool settings come back and mines fine to antpools and resets to root/root. So thought I could use PuTTY to go in and modify the /config/bmminer.conf file to replace the antpool data with my pool and reboot. But when I try to log in with the default root/root I'm told invalid password even though it lets me log into miner from browser using root/root. But even in browser when I try to change password using "root" as current PW, it tells me invalid password???

Bottom line is I can turn on and connects and mines fine to antpool but I can't change the pool settings.

Anybody see before and know how to fix?

Try leaving current password blank.

Verify your pool URL is correct. Also, try just hitting "save" after putting in the URL and then hit "Save & Apply".

The ssh credentials are root/admin not root/root

SSH login with root/root works with all other controller boards, just not this particular one. Temporarily switched out with known good board and could acces through SSH and worked fine. Turns out it's a bad board. Can't buy R4 board anymore but ordered an S9 board. Read that they can be loaded with the R4 firmware and will work.
