<div dir="auto">I have a very strange problem with one of our Dovecot servers (2.2.33.2) on Ubuntu 18.04.<br />
<br />
The current configuration allows for TLSv1 to TLSv1.3 connections. I can verify those using testssl.sh, the tests will succeed (although correctly mentioning, that TLSv1 and TLSv1.1 should be disabled). Running the tests again after about 5 minutes, the results are different. TLSv1.2 now shows "not offered and downgraded to a weaker protocol".<br />
<br />
Has anybody experienced a similar problem before?</div>
