Thank you very much for taking a look at it! I could also see that the browser cache is used sometimes. Sometimes the jsp is requested from the server, sometimes not. I did several tests again and the behaviour is not very consistent, thus it's hard to get a handle on the problem. I was also thinking about the possibility of a Firefox bug but this wouldn’t explain that: 1) It only happens with Tomcat 10.x and doesn’t show up with Tomcat 9.x 2) Users don’t report any problems with other internet websites (using Firefox) The GoAway seems to be sent from time to time by Tomcat, but not always. I recorded one session which matches my last description: https://privfile.com/download.php?fid=62c3ec1170199-MTM2OTM= I set up another PC for testing, thus the IP addresses (source/target) differ and can be interpreted more easily. Maybe the last Capture was not readable without the keyfile, thus I exported it differently and it should be readable now. a) Is the behaviour according to the linked network trace an expected behaviour? (sending a GoAway after a rst_stream message) b) Have you been able to reproduce the error with Tomcat 9.x? If you have any hints or suggestions, how I could narrow it down, please drop a line. I don’t have any big or great ideas at the moment. Thank you very much!
