Wireless Clients randomly get disconnected and has DHCP issues with Cisco APs.

We currently have 2600 and 2800 APs connected to a Cisco 5520 Wireless Controller. But we have issues where wireless clients get randomly get disconnected and referred to as "DHCP issues", but then nothing is wrong with our DHCP scopes. Could this be client authentication, dot1x issue, please help, any support recommendations would be helpful. I have CLI access to WLC, APs, and all network devices. Some of the logs i retrieved are the following from today 06/27/2019:

%EMWEB-6-HTTP_REQ_BEGIN_ERR: http_parser

%APF-4-ASSOCREQ_PROC_FAILED: apf_80211.c:

%DOT1X-4-MAX_EAPOL_KEY_RETRANS: 1x_pt

%APF-4-MOBILESTATION_NOT_FOUND: apf_ms

%EMWEB-6-PARSE_ERROR: webauth_redirect.c:2222 parser exited

On the WLC enter the following command the next time a client has the problem:
show client detail macaddressofclienthavingtheproblem

That might show more about what is wrong.
Which software version is running on the WLC?
