CH keeper-client doesn't connect to secure Keeper port 9281

[DimensionWieldr]

✅ I checked the Altinity Stable Builds lifecycle table, and the Altinity Stable Build version I'm using is still supported.

Type of problem

Bug report - something's broken

Describe the situation

Trying to connect to Keeper's secure port using clickhouse keeper-client runs into a certificate loading error.

How to reproduce the behavior

• altinity/clickhouse-server:25.3.8.30001.altinityfips
• Make sure CH configs only expose secure Keeper port 9281, not 9181 (explicitly remove 9181 with an xml remove clause)
• Try to connect to Keeper using clickhouse keeper-client

Expected behavior

I connect successfully and am able to run queries.

This might be an issue on more versions than just FIPS.
