Unable to start IP warming process

[SachinJ]

Hi Folks,

Greetings!

We are trying to strart IP warming phases and following steps is complete and tested internally but giving us error while running on phases :
- Audience Created with profiles to be targted for IP warming
- Campaigns created with above audience creation
- Email Channel configuration completed and tested for delivery.
- Created IP warming plan beginning with phase 1 and using #2 campaigns created for Ip warming schedule.

While I am waiting for IP warming phase to kick in, I am getting below error where the message is:

"The server encountered an internal error and could not execute the run. Duplicate the run to schedule activation at a later date and time."

I did re-run by duplicating the failed ones, and also adjusted the time as per audience evaluation.

My audience is evaluated and ready around 7:30PM EST time and I am running the phase at 9:30/10:30PM EST time to begin IP warming.

Even After multiple Attempts I face same error and support is also not helping to great extent to find out why and what could be potential reasons.

I rely on community Engineers to help me get the right direction to debug this issue and resolve.
