Error: Reentrance_Ticket: cannot create SAP logon ticket

Hi folks,

When I run the transaction solman_workcenter a log on screen pops up with the following warning messages:

Protocol cannot be switched to HTTPS; HTPPS is not configured/active

No switch to HTTPS occured, so it is not secure to send a password

I have already checked the parameters:

login/accept_sso2_ticket = 1

icm/server_port_1 = PROT=HTTPS,PORT=8001,TIMEOUT=180

what am I missing to configure?

Tks,

Má
