Отредактирована: сегодня

Symptoms

When performing any actions in Swarmica, the following error appears:

"message": "Request failed with status code 502",
 "response": {
 \"data\": \"<html><head><title>Error 502</title></head><body><h1>Error 502: EOF while reading response</h1><p></p></body></html>\",
 \"status\": 502,
 \"statusText\": "Bad Gateway",
 \"headers\": {
 \\\"content-length\": "116",
 \\\"content-type\": "text/html; charset=utf-8"
 }
 },

or:

"message": "Request failed with status code 502",
 "response": {
 \"data\": "Bad Gateway",
 \"status\": 502,
 \"statusText\": "",
 \"headers\": {
 \\\"content-length\": "11",

Solution

Check/disable firewall/VPN, etc. Try connecting from another location.

Try setting longer timeouts on the load balancer.

Cause

This error does not come from Swarmica (since the backend application does not even have such an error code), but from a proxy server, NAT, WAF gateway, VPN, etc., somewhere between the user and the Swarmica server.

It may also be related to an external load balancer and short timeouts on it.
