After deployment I try to do several attempts and all of my attempts result is 502 bad gateway
But approximately after 2 minutes although didn't change anything I am able to get response from api.It means that server sent request. I couldn't catch what happened during first attempts and why I got gateway error.
I would like add some notes about request body.I send refresh token into of request and it is 3900 symbol and I checked with devops team, they told me that it is not oversize of proxy size limit
