Hi @abdallahalhakim
I've reviewed the Support case you referenced and it seems like the issue is solved at this time.
Let me take this opportunity to explain why sometimes these certificate renewals can trigger issues with some integrations. If, for example, your integration is pinning our public SSL certificate in your trust store, or if you are not properly importing the root CA per our documentation, this could cause SSL errors following our deployment. Likewise, if your integration code elects to cache SSL certificates (again, contrary to common practice), this could cause SSL errors as well. Most integrations seem to have no issue with this however we have noticed that some do.
If your code was impacted by this issue, I would encourage anyone impacted to please share details here. Else, we could encourage you to work with your internal teams and Zuora support to address any problems you might have encountered.
