Power Platform Community Forum Thread Details

Hi all,
maybe some one can help me with frustrating error. I have created a flow in power automate service (not desktop) that:

connects to a public webpage www.lb.lt/lt/draudikai-veiklos-rodikliai#ex-1-1 (via http action)
saves page body value into current_day variable
then gets txt file from OneDrive with previous day information and put that information into previous_day variable
compares two variables and if there is any changes sends an email
overwrites previuos_day txt file values with current_day values

Super simple flow... but when i test this flow it returns me a Forbidden error. I have added to http action key User-Agent with Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3
And nothing... same Forbidden error

When i try this flow on some other webpages - it works. What can be wrong with www.lb.lt/lt/draudikai-veiklos-rodikliai#ex-1-1 ? Maybe there are some page protections? I'm not that strong on page analysis so I don't see any limitations
Can some one to try to recreate this flow and share with me a solution?
