The Ignite Realtime community has just released Spark 2.8.1 and it can be downloaded from Ignite Realtime: Downloads .
This is a bugfix release for 2.8.0, which has introduced a huge overhaul and created a few new issues. Many users had problems with login after upgrading to 2.8.0. This won't change with 2.8.1. It is not a bug, but rather an incorrect setup. Admittedly, this was introduced because of lack of security check in older Spark\Smack versions. But we can't leave Spark blind to bad or forged certificates (in the age of security breaches and moving all the web to TLS). So, if you have this problems, please read Login issues since Spark 2.8.0 . 2.8.1 is introducing an option "Disable certificate hostname verification (not recommended)" in the Advanced settings of the Login screen. If you can't fix your setup or want a temporary workaround, you can use it. But be warned, that you will make yourself (or your users) less secure. 2.8.0 also introduced new setting "Accept all certificates" in the same place. It was enabled by default for those upgrading from 2.7.7. It automatically accepts self-signed and some other incorrect certificates (expired, etc.). This was done to make 2.8.0 backwards compatible, if you were using self-signed certificates provided by Openfire. This setting will stay enabled after 2.8.1 update. But there is a plan to make it disabled by default for new installations in 2.8.2 version.
