Hiya BlackBlade,

Your secondlife.log file shows a login time out on Second Life Release 6.4.0.540188

• Login button clicked at 18:54:56
  2020-04-21T18:54:56Z INFO #AppInit# newview/llstartup.cpp(898) idle_startup : Attempting login as: blackblade_smit

• Inventory started loading from cache at 18:55:23 (1 sec slapsed since login request - fine).

• Inventory finished loading from cache at 18:55:30 (took 7 secs to load - bit slow but not terrible if you have a large inventory).

• Creating inventory views took 49 seconds. This is much too long & indicates you have a very "flat" inventory structure.
• Total login time is already 1 min 24 secs & this is right on the edge of being so long your login will time out already.
• Another 20 seconds elapses between:

    Why???

• Login then times out due to it taking too long.

Linden Lab support should be able to fix this problem for you by running a script that "deflattens" your inventory.
If you are a premium member, you can contact Live Chat & get your inventory fixed straight away.
If you are a basic member, you will need to file a support ticket to request that your inventory is deflattened.
How to contact LL support: https://lindenlab.freshdesk.com/support/solutions/articles/31000131009-contact-support

There is a known problem with large & extremely flat inventories causing logins to time out because the "creating inventory views" from your inventory cache takes too long.
A flat inventory is one where one or more inventory folders have too many items in them, where an item is a loose asset or a folder.
The deflatten tool LL support uses creates subfolders in your inventory & moves inventory items into the subfolders where needed - I think this happens when any single folder contains more than 1000 items.
I've had my own inventory deflattened & it's fine, so don't worry. It actually makes your inventory easier to organize yourself :)

I saw your forum thread where you reported that you only suffer from the login timeout on the LL EEP viewer and that the previous LL viewer before the EEP update didn't suffer from this problem.
I suspect strongly that You were very close to a login timeout on the viewer before EEP, but the slightly longer login times on the EEP viewer have just pushed you over the edge.
I've noticed myself that EEP viewers have longer login times & this is something that LL should maybe investigate.

Should be significantly better in upcoming maint viewer DRTVWR-507.
