Unable to open web UI

Hi there,
I am new to Hassio, after configuring hassio on pi3+, I installed Log viewer. It gets successfully installed but I am unable to open webUI of log viewer with port 4277. As according to instruction I done the same. What I am doing wrong.

Assume that a) you have valid userid and password defined in the logviewer definition and also that you have opened port 4277 on your router.
If your accessing the logviewer from iframe you will reference the access url, if you are using duckdns then you need to ensure that it is the https address.

Hello Isablend,
Yes I have valid username and password and not using duckdns. Opened port 4277, I not got it.

might be useful to share your logviewer config (minus id and pswd). Also what url is displayed when you click the webui link?

Thank you Isablend,
Now I got it, I am writing Password which is used many time on my account, I changed a little bit and done successfully.
