<br>
I have one backend:<br>
<br>
upstream backend_1 {<br>
server <a href="http://127.0.0.1:35510" rel="noreferrer" target="_blank">127.0.0.1:35510</a>;<br>
}<br>
<br>
and server:<br>
<br>
server {<br>
...<br>
location / {<br>
proxy_pass <a href="http://backend_1" rel="noreferrer" target="_blank">http://backend_1</a>;<br>
}<br>
}<br>
<br>
<br>
Sometimes I have to restart my backend and it is unavailable for 3-5sec<br>
(port unreachable)<br>
<br>
How I can tell nginx to "wait" for backend and do not respond with 502 ?<br>
So it should hold connection for 5 second and if it is unreachable in that<br>
interval responds 502 to client.<br>
<br>
Thanks<br>
<br>
