Code 422: "certificate has expired"

Dear all,

I have inherited a system that integrates Rapidpro and AWS SMS Gateway (Lambda service). However, I am currently experiencing issues as I am unable to access the EC2 through SSH. When trying to access it, I receive the error code 422, which states that the certificate has expired.

The error message seems to be coming from Rapidpro, and it is causing the SMS Gateway to fail when processing the information. Could someone please assist me in resolving this issue? Thank you. ** { "message": { "provider": "rapidpro", "content": "idsr 0404 nve0=0|inC5=0|Kne0=10|ZyCi=0|sMe0=0|F1jp=0|zSC5=0|JyCi=0|u1p6=3-1-2|ibC5=0|nEC5=0|wWe0=6|F1C5=0|Zye0=0|ODe0=0|wWC5=0|nvC5=0|Knjp=11|ibjp=0|nEjp=0|wWjp=1|dxCi=0|sMjp=0|KnC5=0|sMC5=0|nvjp=0|ODCi=0|lYjp=0|u6C5=0|KPjp=0|fae0=0|ZoC5=0|lYC5=0|u6jp=0|F1Ci=0|KPC5=0|Epe0=0|faC5=0|KnCi=0|ibCi=0|nECi=0|fajp=0|Epjp=0|nEe0=0|wWCi=0|ibe0=0|sMCi=0|F1e0=0|EpC5=0|zSe0=0|nvCi=0|gqjp=0|PcC5=0|lYCi=0|dHjp=0|wDjp=0|hVjp=0|zMe0=0|wDC5=0|KPCi=0|BRjp=0|Rxp6=1|gqC5=0|FHe0=0|u6Ci=0|RZe0=10|ETp6=2020-06-20 17:00:52|Ftjp=0|kGe0=0|dHC5=0|Pce0=0|EZjp=0|zMC5=0|zMjp=0|BRe0=0|RZjp=11|lYe0=0|Bpp6=false|xLp6=2020-06-20 17:00:52|faCi=0|EpCi=0|kGjp=0|KPe0=0|FHC5=0|u6e0=0|BRC5=0|kGC5=0|gqCi=0|EZe0=0|ODC5=0|dHCi=0|wDCi=0|hVCi=0|BRCi=0|dxC5=0|Zyjp=0|dxe0=0|FtCi=0|ZyC5=0|EZCi=0|g1p6=africell|dCC5=0|dHe0=0|zMCi=0|FtC5=0|gqe0=0|EZC5=0|hVe0=0|vHp6=kwellu_ngieya|wDe0=0|hVC5=0|kGCi=0|dxjp=0|Fte0=0|drp6=Mobile_SMS|ODjp=0|", "to_number": "8640", "from_number": "+23299913152", "id": "e6cc97e3-c1c3-423f-a778-a571f3371a7c", "time": "2023-04-09T06:14:04.905", "reqid": "e845c015-f36a-4c16-a2a0-31c4e6a0294b", "direction": "incoming", "status": "error", "wasCompressed": true, "error": { "name": "Error", "message": "certificate has expired", "code": 422 } }, "level": "error", "label": "sms-gateway-prod", "timestamp": "2023-04-09T06:14:11.033Z" }**
