Error on backend node js (nest.js)

hello everyone I have decided to ask for help here. I have uploaded my website on railway about 5 months ago, the last deployment was 5 months ago, but today I had a problem with my website. I was checking the backend logs and I found the following: [Nest] 32 - 02/21/2024, 12:11:54 AM ERROR [ExceptionsHandler] connect ECONNREFUSED 35.230.73.152:7717 Error: connect ECONNREFUSED 35.230.73.152:7717 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1278:16) I have developed my backend with nest.js, I have also noticed that this error message has appeared before in the logs: [Nest] 32 - 02/14/2024, 5:26:30 AM ERROR [ExceptionsHandler] connect ECONNREFUSED 35.230.73.152:7717 Error: connect ECONNREFUSED 35.230.73.152:7717 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1278:16) please help me I have no idea how to fix it.
