SharePoint Events webpart error "There may be too many sites selected or too many filters added."

[unnie ayilliath]

Hello,

In our Intranet (Hub site), we started getting below error in events webpart (view all page):

"There may be too many sites selected or too many filters added. Try Selecting fewer sites or remove some filters to continue."

The events webpart is configured to show events from all sites in the Hub. There are around 51 site collections associated to this hub. 

Anyone experienced same problem and have some tips on this?

Hi,
I have seen this problem also in some of my sites....it seems a temporary GitHub.

@Juan Carlos González Martín Yea, the issue got resolved after couple of days. But strange

I got this when I select the 39th site to add to the Events web part. Select 38 sites, it's fine, 39 and it throws this same error. Quite annoying as I've a news web part right above it with 42 sites selected and working ok.
