@DamianMaslanka5 @Felixoid could we revert the changes in #73705 ? I see there is a note in docs_check.py to remove some code once all the broken hashes are fixed. I believe all are fixed now, and it's now failing on hashes which I cannot even find in the code.

[Felixoid]

I'd suggest fixing them.

In this case, we need to search in https://github.com/ClickHouse/clickhouse-docs/, and there are the anchors we need to fix:

> git grep obtain-gcp-service-attachment-for-private-service-connect
docs/en/cloud/security/gcp-private-service-connect.md:TARGET - Use **endpointServiceId** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step
docs/en/cloud/security/gcp-private-service-connect.md:DNS_RECORD - use **privateDnsHostname** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step
docs/en/cloud/security/gcp-private-service-connect.md:DNS_NAME - Use **privateDnsHostname** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step
docs/en/cloud/security/gcp-private-service-connect.md:DNS_RECORD - Use **privateDnsHostname** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step
docs/en/cloud/security/gcp-private-service-connect.md:Each instance with configured Private Service Connect filters has two endpoints: public and private. In order to connect using Private Service Connect, you need to use a private endpoint, see use **endpointServiceId** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step
docs/en/cloud/security/gcp-private-service-connect.md:DNS_NAME - Use **privateDnsHostname** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step
docs/en/cloud/security/gcp-private-service-connect.md:DNS_NAME - Use **privateDnsHostname** from [Obtain GCP service attachment for Private Service Connect](#obtain-gcp-service-attachment-for-private-service-connect) step

I think, other broken anchors could be found similarly.
