Hi All,

We are using FCM HTTP v1 API from last 1.5 years to push notifications but from last 4-5 days, 15 September onward we are getting 502 error intermittently. 

This error is coming in between when we push notifications to 1 Lakh users in batch of 1000 each then for few batches we get 502 error.

API response is as below mentioned:

<!DOCTYPE html>
<html lang=en>
 
<meta charset=utf-8>
 
<meta name=viewport content="initial-scale=1, minimum-scale=1, width=device-width">

<p><b>502.</b> <ins>That’s an error.</ins>
 
<p>The server encountered a temporary error and could not complete your request.<p>Please try again in 30 seconds.  <ins>That’s all we know.</ins>

It would be great help if anyone can help to resolve this issue.

Thanks.

Probably best to file this one with the support team to investigate. https://firebase.google.com/support/contact/?category=troubleshooting
