Pushover LM2.3 and LM2.4

[SigmaTec]

Hi all,

I updated my WiserForKnx controler from v2.3 to v2.4 and since this upgrade the Pushover function doesn't work.

The Lua line 
local res, code, headers, status = ssl.https.request(pushover_url, data_str)

Give with log
res : nil
code : "Try again"
headers : nil
status : nil

using directly functions on Pushover.net website, all I ok.
So, user_name and token are corrects.

Any idea ?

Thank's in advance.
