Whenever I try and access Xanathar's Guide to Everything, I can get the table of contents page to open, but if I click on anything, I get an Error page:

"This page isn't working

www.dndbeyond.com redirected you too many times.

Try deleting your cookies.

ER_TOO_MANY_REDIRECTS"

I deleted my cookies and got it to open once, but after that, I get the message again.

this only happens for this book. everything everything else Ive tried works fine.

Win11 using Chrome Version 126.0.6478.127

Log out of D&D Beyond.

Clear all cookies and cache.

Close browser.

Re-open browser and re-login to D&D Beyond to try again.

If not working after that try checking extensions and VPNs.

This error occurs when you have outdated or corrupted cookies or cache for the page in your browser's memory. On very rare occasions it can be caused by interference from browser extensions or VPNs. It has nothing to do with D&D Beyond itself.

Same results. I can get it to load once, but after that it errors. Being every other source works just fine, I think it may be something wrong with Xanathar's specifically.

It's not.

That error cannot be produced by a page to affect just you. It would affect everyone who ever visits it. And since that isn't happening, and it is a browser-memory issue, this is very much a "you" thing not a "D&D Beyond thing". 

unless it was a combination of factors that only effect a smaller number of people. If it was just a me thing, I would expect the same results on at least one other source book. but I've checked all that I have access to with no problem. Only this one book has this problem.

I am constantly having this issue. Did you ever get it fixed?

I am also having this issue, and Have tried the above fixes.
