Unable to Edit Confluence Page

[siva ramakrishna]

We are unable to edit confluence pages and getting some unknown errors. We have tried following the below steps but stills issue not solved permanently. Sometimes its working and sometimes it's not working. 

• Clear all browser cache and disable all addons from the previous browser being used
• Try and use incognito/private mode of your previous browser

Please find the below details and provide an update.

1. Do you happen to have a proxy of firewall in your current environment? -- Yes, we are using Client VPN. 
2. Is there someone else who is currently facing the same behavior? Yes, almost all users who can edit earlier. 
3. Has this worked in the past? yes, users are able to access the same about few months. 
4. Is this present regardless of device used to interact with Confluence? yes
5. Is this present regardless of internet connection used to connect to Confluence? Yes
6. Are you still facing this issue? Yes, all the Team members are facing this issue since one month.

Hi @siva ramakrishna  and welcome to the Community!

Are you a Confluence Admin in your instance?

The Server will be set to Read-Only if you reached your licenced user limits. If Admins are adding/removing people - or maybe that happens because Users get synched automatically - that might explain, why this is an On/Off Behaviour?

Usually that gives you a clear error message though.
