Error: You are using an outdated browser that is not supported by COYO

I was using the create PDF from webpage function, I entered the webpage url and started creating. Later there was an error happened saying "You are using an outdated browser that is not supported by COYO". My colleague tried also from his laptop, and the error was the same.

I believe COYO is a security app that was forced by my company. I contacted them, they checked all of my browsers and said there was no problem. They suggested I contact Adobe. 

My OS is WIN10, 3 browsers as below,
Chrome Version 92.0.4515.107 (Official Build) (64-bit)
Firefox 78.12.0esr (32-bit)
Edge Version 92.0.902.55 (Official build) (64-bit)

My adobe says "no updated available". The current version is Adobe Acrobat 2017 (17.011.30199)

And my colleague is also using WIN10, with two browsers,
Firefox 90.0 (64-bit)
Edge Version 91.0.864.71 (Official build) (64-bit)

My colleague's Adobe was downloaded from your website last Thursday, I don't think it should be out of date.
