Hi,

two weeks ago my Miro boards stopped loading. Reason is the browser is not trusting mirostatic.com that serves all the board elements (html, javascript). Mirostatic.com seems to have no valid certificate.

Error: ERR_CERT_AUTHORITY_INVALID for mirostatic.com - no valid certificate

How to fix this?

try on another browser like opera o edge.

if not continues giving go on incongniyo mode.


Nothing works. The site is blocked by corporate firewalls just because of invalid certificates of mirostatic.com. Miro has to fix that.

Hi ​@Steffen König, thanks for reporting this!

 

I will go ahead and convert your case into a support ticket so our technical team can investigate further and assist you directly—especially given that this may involve certificate validation on corporate networks.

You’ll receive a follow-up via email shortly. We appreciate your patience, and we’ll do our best to help you get access to your boards again as soon as possible.
