Bad Request - HTTP Error 400. The size of the request headers is too long. Error inserting Photos

Copper Contributor

I'm unable to insert or change photos to online photos in 

Microsoft® Word 2016 MSO (Version 2403 Build 16.0.17425.20058) 64-bit


Steps to reproduce: 

1. Open blank document.

2. Choose Insert from menu

3. Choose Pictures

4.  Choose Online Pictures.


This is where I get the error:

Bad Request - Request Too Long

HTTP Error 400. The size of the request headers is too long.

Well I figured it out myself. No replies here but I'll post what I found. I went to C:\Users\4corb\AppData\Local\Google\Chrome\User Data\Default\Network on my Windows 11  machine and created a Archive folder and moved the Cookies file into that folder. (To protect myself in case it caused an issue) I opened word and voila no more error. 

I also have this error when inserting a background in Excel (Page Layout Tab >> Page Configuration >> Background). The command didn't solve the problem, nor did cleaning the temp folder.

Também estou com este erro no inserir plano de fundo no Excel (Guia Layout de Páginas >> Configuração de Páginas >> Plano de Fundo). O comando não resolveu e nem limpando a pasta temp.
