Hi, please enlarge the settings for the configuration: MDNS_MAX_SERVICES, and then have a try.

[zwx1995esp]

Hi, we have already enlarged the default configuration for the max mdns service. Please see the commit: 4844efcf7aed4249dfd3585912c6ab8bb6b9a522. Will close this issue, but if you encounter any other problems, feel free to open another issue. Thanks a lot.
