Describe the issue

From my iPhone and iPad I can not connect to ROON ARC, but can connect to ROON. On my ROON server (MacBook Air) is under setting/ROON ARC following message: {
"ipv4_connectivity": {"status":"NetworkError","status_code":504,"error":"error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined"},
"external_ip": {"actual_external_ip":"176.aaa.bbb.ccc","actual_external_ipv6":"null","router_external_ip":"null"},
"natpmp_autoconfig": {"status":"NotFound"},
"upnp_autoconfig": {"status":"NotFound"}
}
I have DECO router from TP-LINK with wifi 6 mesh. I rebooted all my stations, including server - no change.
I worked well, but recently I connected to VPN (NordVPN) and it may cause those problems.
Also when on ROON on my iPad or iPhone 13 PRO MAX - I can connect to ROON serves on my MacBook Air, but I do not see my iPhone or iPad in Settings/Audio - also do not know why.....
Please advice. Thank you very much. Radek

Hey @Radek_Sabela,

Welcome to the community! We’re excited to have you here.

but recently I connected to VPN (NordVPN)

An important note here - the use of VPNs or VLANs falls outside the scope of Roon Technical Support. With this, I’ve moved you thread into the proper category - Tinkering where other users in the Roon community who use VPNs may be able to step in and help provide some additional information.

Thanks for your understanding!
