Cannot open Yun homepage

When opening the Yun homepage I see this message:

?:0: attempt to index a nil value
stack traceback:
	?: in function 'read_gpg_pub_key'
	?: in function <?:144>
	?: in function 'dispatch'
	?: in function <?:194>

What is this and how can I solve this?

Running sketches and using HttpClient is working.

I've seen that message only right after I powered the yun on. Have you tried refreshing the page?

Hello, i just reboot my Yun and i get the same message !
what can i do now ? please advise

Usually you just need to wait a few seconds and refresh

Hello all

Posting this because I just had a similar Problem:

?:0: attempt to index a nil value
stack traceback:
?: in function 'read_gpg_pub_key'
?: in function 'authen'
/usr/lib/lua/luci/dispatcher.lua:370: in function 'dispatch'
/usr/lib/lua/luci/dispatcher.lua:195: in function </usr/lib/lua/luci/dispatcher.lua:194>

Solved it by pressing at least for 30sec the WLAN RST (next to USB) on my Arduino Yun
