External indexer certificates are too short-lived.
In an attempt to fix PAM-11122, the default lifetime of several certificates was limited to 800 days, because browsers did not trust certificates with a longer validity period. Due to an error, the lifetime of the external indexer SSL certificate was limited too, despite its sole use was to encrypt the traffic between the external indexers and SPS, where web browsers are not involved.
However, after the external indexer SSL certificate expires, the external indexers will not be able to connect to SPS, and external indexing stops working. The workaround is to reconfigure the external indexers by disabling and re-enabling external indexing and resetting the external indexer configurations.
You are only affected by this issue if you enabled external indexing while running SPS version 6.0.4/6.4.0 or later, when the fix for PAM-11122 was released, since previous versions included external indexer certificates with a sufficiently long lifetime.
After the current fix, freshly generated external indexer certificates will again have a lifetime of 20 years. |
