The request signature we calculated does not match the signature you provided. Check your key and signing method

Compactor job for anonymous tenant is suddenly failing for the last 3 hours.
When i checked the logs i found this:
ts=2024-04-10T04:15:22.910975155Z caller=compactor.go:652 level=error component=compactor msg="failed to compact user blocks" user=anonymous err="compaction: group 0@17241709254077376921-merge--1712620800000-1712707200000: upload of 01HV338YMFDMZYM4J0PKS06GFK failed: upload chunks: upload file /data/compact/0@17241709254077376921-merge--1712620800000-1712707200000/01HV338YMFDMZYM4J0PKS06GFK/chunks/000002 as 01HV338YMFDMZYM4J0PKS06GFK/chunks/000002: upload s3 object: The request signature we calculated does not match the signature you provided. Check your key and signing method."

Why is the signature mismatching just for the last 3 hours?
I have not changed any configurations.

Note: Multi-tenancy is enabled.

There is no such error for other tenants.

Thanks in advance.
