Reverse-proxy doesn't run

[andrey-nosan]

Hello!
Great job! Thank you for it!

I've cloned this project and tried to set up it on my Linux machine, and... I have some problem.
Containers site1 and site2 run normally, ok, but container reverse-proxy shuts down in few seconds after the start.
I've investigated problem and identified that it happens when there are lines
proxy_pass http://site1_app_1;
and
proxy_pass http://site2_app_2;
in default.conf

Please advise how to fix it?
I'm not enough strong in Nginx )))

Thank you in advance!

In the default.conf add this line line at the top of the file server_names_hash_bucket_size 64;

I fixed it by modifying both lines to:
proxy_pass http://site1-app-1;
and
proxy_pass http://site2-app-1;
