Not able to connect to Gen8 iLO4 with the REST client #72

Closed nlin24 closed 5 years ago

nlin24 commented 5 years ago

Hello,

I am having trouble establishing a connection to a Gen8 iLO4 and wanted to see if anybody has a resolution to it. My script seems to work with Gen9 iLO4, with iLO Advanced Limited NRF, firmware version at 2.61 July 27 2018, but for unknown reason I can't get it to connect with a DL360 Gen8 iLO4, with iLO Advanced license, and firmware version at 2.55 Aug 16 2017. It fails for protocol error. I'm able to SSH to the Gen8 iLO4 and also access its web GUI. I am running on Ubuntu 18 LTS and Python 3.6.8. Any suggestions? Thanks in advance.

Error message:

@Yergidy hey, I tried accessing the APIs on Gen8 again using the requests module; it seems to fail for Protocol Error as well. Please see below for more detail. Any thought? Thanks.

@nlin24 Just to be sure, you are using the iLO IP to connect and not the SSH IP?

nlin24 commented 5 years ago

Hey @Yergidy we got it working. It's a weird one, such that we observed the error on Gen8 occurs on Python 3.6.8 but not on Python 3.8.0. Not sure what's the root cause but seems to be Python interpreter related. Will probably just not-use version 3.6.8. Shall I go ahead and I close the ticket? Thanks.

By the way, yes, I am 100% sure I had the correct iLO IP and login credentials.

If you root caused the issue back to Python 3.6.8 you can close. Thanks!
