Hello @cthivierge ,
Thanks for the question and using MS Q&A platform.
My understanding is that you are noticing communication issues after updating the SHIR. Please correct if I'm wrong.
Could you please confirm if the issue happens only during or right after SHIR is upgraded and issue auto resolves after that or the issue persists consistently?
In general, if there are any bugs in the latest released version of SHIR then you might see issues, but if you are seeing communication issues everytime you upgrade the SHIR, then I assume it could be something else. Many factors may result in SHIR communication issues as SHIR is customer managed and not Azure managed.
In order to further troubleshoot the issue, I would recommend to please go through this troubleshooting guide and see if if provides any relevant information with respect to your scenario. But if you feel if didn't help, then I recommend filing a support ticket and share the SHIR logs by gathering them as mentioned in here: Gather self-hosted IR logs, so that the support engineer can take a deeper look in to SHIR logs to figure out the root cause and provide possible solution.
And in case if you don't have a support plan, please let me know here.
Thank you
