All chromecast speakers show hourglass after 2.6.0b2

[mptpro]

Got home today and tried playing to my chromecast devices (speakers, display and chromecasts) but none worked. I saw that MA was updated to version 2.6.0b2, so perhaps this is the cause?

• All was working this morning before I left the house.
• In Settings/Players all of the chromecast devices show an hourglass (see screenshot below).
• I looked in the logs and I did see this error:

WARNING (MainThread) [zeroconf] No buffer space available when adding 172.27.0.1 to multicast group, try increasing net.ipv4.igmp_max_membershipsto1024 in sysctl.conf

• I am using Docker on Linux.
• I have restarted MA serveral times.
• I have unplugged all my chromecast devices.

I’d say the answer is given to you. Google that error and you will see many solutions. Here is the first https://community.home-assistant.io/t/zeroconf-error/153883

I also have alot of hourglas on my Chromecast devices, i run HAOS in VM on Proxmox. Trying different solution without luck, my speakers are still on "hourglas".

I do see 2-3 available to play on, and these are different (most of the time) on every reboot, but the rest of my 7-8 (total 11) is not usable.
