Since about 2 weeks we are getting intermittent 502's from two of our Azure Functions. We are unable to track it to any code changes (one service hasn't been re-deployed in over a month). To mitigate we have tried restarting and re-deploying one of the affected services but we are still seeing intermittent 502s being reported to the Function users.
To add, we have also seen sporadic reboots of one of the Functions that we can't correlate to any of our actions.
Anyone else seeing this?
How can we resolve this?
Consumption plan.

2024-04-29T09:08:37.9733333+00:00 I am still seeing this, with a slight increase, and can't understand why the Azure Function would respond with 502 to the clients. I am far from hitting any limits.
Does anyone know to troubleshoot his more?
Are there more diagnostics available from the load balancer/gateway that runs in front of an Azure Function?Also want to repeat that the issues are intermittent and are affecting services that hasn't been re-deployed near in time to when the issues started. Issues started during this maintenance window: https://app.azure.com/h/BKPG-FZZ/a8bb20

And also use Application Insights to check the "Failures" blade, the full stack exception message may be found there.
@Thomas Rosdahl can you share the support ticket number? I may be able to ask the support team for an update.
