In addition, you have more technologies and this means more problems.<br \/>I adopted HTML5 long time ago and everything worked fine for a long time. I have to say, that it was better that I expected. But now I have to change the certificate. Well, this is not a complicated job\u2026 or it is? The answer is yes, it is. <br \/>I have changed my certificate as usual, form server manager. I tried to connect to website and everything was OK.

So, if I had changed the certificate, I have to register a new one \u2013 rerun PowerShell cmdlet &#8212;&#8212; .<br \/>This apparently didn\u2019t solve my issue because from my computer it seems the situation haven\u2019t change. But then a customer tried to work from a new computer and it worked! Why???<br \/>The reason was in cookies and cache files on the computer browser! Yes, you have to delete all cookies and cache files and (at least in my case) the webpage will work again. <\/p>\n<p><a href=\"https:\/\/em-soft.si\/myblog\/elvis\/?attachment_id=986\" rel=\"attachment wp-att-986\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-986\" src=\"https:\/\/em-soft.si\/myblog\/elvis\/wp-content\/uploads\/2019\/09\/Firefox_HTML5.png\" alt=\"RDP HTML5 Firefox setting\" width=\"650\" height=\"171\"\/><\/a> <a href=\"https:\/\/em-soft.si\/myblog\/elvis\/?attachment_id=987\" rel=\"attachment wp-att-987\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-987 size-full\" src=\"https:\/\/em-soft.si\/myblog\/elvis\/wp-content\/uploads\/2019\/09\/Edge_HTML5.png\" alt=\"RDP HTML5 Edge setting\" width=\"399\" height=\"458\"\/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you are using HTML5 web site for remote apps and you have to change a certificate, you may expect some problems.This technology is pretty new and there are not so many posts on internet, so troubleshooting could be difficult.
