Especially when working over SSL this limit can be reached pretty quickly and I think. I’d suggest setting a value of around 10 MB to align with your 8MB upload limits. * Please let me know if this solves the issue * Thanks Thorsten Viewing 15 replies - 1 through 15 (of 27 total) 1 [2](https://wordpress.org/support/topic/http-error-99/page/2/?output_format=md) [→](https://wordpress.org/support/topic/http-error-99/page/2/?output_format=md) The topic ‘HTTP error’ is closed to new replies. * ![](https://ps.w.org/windows-azure-storage/assets/icon-256x256.png?rev=2486101) * [Microsoft Azure Storage for WordPress](https://wordpress.org/plugins/windows-azure-storage/) * [Support Threads](https://wordpress.org/support/plugin/windows-azure-storage/) * [Active Topics](https://wordpress.org/support/plugin/windows-azure-storage/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/windows-azure-storage/unresolved/) * [Reviews](https://wordpress.org/support/plugin/windows-azure-storage/reviews/) * 27 replies * 3 participants * Last reply from: [setevoy](https://wordpress.org/support/users/setevoy/) * Last activity: [9 years, 4 months ago](https://wordpress.org/support/topic/http-error-99/page/2/#post-8492805) * Status: resolved
