SSL certificate problem: unable to get local issuer certificate

[minhbaop]

Hi,
My S3 compatible provider's SSL certificate expired about 26h ago, after that they renew SSL certificate. But my Nextcloud app still don't update new duration SSL certificate and I have error:
"There was an error with message: Exception: Creation of bucket "nextcloud1" failed. Error executing "CreateBucket" on "https://nextcloud1.s3-hcm-r1.longvan.net/"; AWS HTTP error: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html). Do you want to review mount point config in admin settings page?"
Please help me how to fix it.
Thanks

@minhbaop https://nextcloud1.s3-hcm-r1.longvan.net/ still has a self-signed certificate. Is that expected?

No, This certificate is OK. Sectigo RSA Domain Validation Secure Server CA .
I've tried to migrate my 2 apps to other server but the error certificate is exist. Maybe my apps (rocket chat & nextcloud ) don't update new status CA of S3 Storage https://nextcloud1.s3-hcm-r1.longvan.net/. Maybe some other cache issue somewhere ?
Please show me how to clear cache of CA external server .
Thanks

Did you add the S3 storage inside the apps? If so, maybe a restart of the apps help? AFAIK, apps usually don't cache cert information but I could be wrong.

@girish Hi, everything is ok now, after my s3 storage provider fixed their S3 error SSL certificate .
Thanks
