Cann´t access my router 50-7B-9D-66-03-B4

Hey guys!
I wanted to access my router in Google Chrome, i checked the ip address and enterd it. But I always get the error " “ip of the router” denied connection". I don´t really have an idea what the problem could be. I hope you can help me.

Thanks for your help in advance!

You mention IP address (and a web browser expects an IP address or a domain name), but you’ve posted a MAC address in the subject of the topic.

If you do enter the actual IP address of the router to the browser, it is possible that the firewall rules or other settings on the router make it reject the connection. Can you access the router any other way (Winbox)? If yes, post the export of its configuration as suggested in my automatic signature below.
