<p dir="auto">Hi <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/piotrgregor/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/piotrgregor">@piotrgregor</a></p>
<p dir="auto">The whole reason I started digging into this is precisely because I was seeing this in Kamailio logs</p>
<p dir="auto">ERROR: stirshaken [stirshaken_mod.c:488]: ki_stirshaken_check_identity(): SIP Identity Header did not pass verification<br>
ERROR: stirshaken [stirshaken_mod.c:560]: ki_stirshaken_check_identity(): identity check: fail</p>
<p dir="auto">Upon investigation I determined this happened any time a certificate was cached that relied on a chain.  The first call will succeed but any subsequent calls fail until the cached certificate expires or is manually deleted.  Then the next call will validate ok, but subsequent calls fail.</p>
<p dir="auto">This happens today with 5.6.2 on my unpatched machine.</p>
